Tattoo Ideas
Heart
Two unrelated design problems share one word. The symbolic heart is a flat graphic shape with a flash lineage older than almost anything else in Western tattooing. The anatomical heart is a rendering exercise in vessels and muscle. Twelve directions, why the Mom banner outlives partner names, and where the Sacred Heart splits off into its own iconography.
Book a consultationSymbol or organ
There are two hearts, and they aren’t related.
Nearly every heart booking is one of two completely separate jobs, and most clients don’t know which one they’re in when they walk through the door. The symbol is a graphic mark: two lobes and a point. The organ is an object with chambers, vessels and a particular silhouette. They share a name and almost nothing else. Different reference material, different floor size, different artists. Sort this before anything below it.
The symbol is a sign, not a picture
Nobody can say for certain where the two-lobed shape came from; it turns up in European manuscript illumination and heraldry from the medieval period and it has never looked much like the organ it stands for. That’s the useful part. It behaves like a letterform. All the quality in a symbol heart sits in the curve of the two shoulders and the sharpness of the point, and no amount of shading rescues a bad one. Traditional artists lay it in from muscle memory or a template for exactly that reason.
The organ needs the room an object needs
An anatomical heart carries aorta, pulmonary trunk, atria, ventricles and a fatty surface with coronary vessels running across it. Four inches is roughly the floor. Below that the vessels merge into the outline and the whole thing reads as a lumpy fist. It also wants black-and-gray far more than color, because everything identifying it is a change in value rather than a line. Bring an actual anatomical plate as reference, not a stylized drawing of one.
Banner-and-heart is the oldest sentimental tattoo in the Western repertoire
A heart with a scroll across it and a name lettered inside. It predates most of what people picture when they picture classic flash, and it survived because it does one job cleanly: it names a person while giving the artist a solid red-and-black anchor that reads across a room. The banner solves a technical problem too. Lettering on its own softens into an unreadable smudge over decades, but lettering held inside a bold shape stays legible, because the shape keeps carrying the composition after the letters go soft.
Why “Mom” survives and a partner’s name doesn’t
It isn’t sentiment. It’s structure. The relationship a Mom banner names doesn’t end, so the tattoo never becomes something you have to explain or hide. Partner-name hearts are the single most common cover-up request in any working shop, and the ones that cover easily were built to. If you want a name in a heart, ask for the heart to compose without it: shape, shading and surrounding elements all holding together on their own. Then a cover-up, if it ever comes, is a short session rather than a fresh tattoo.
The black-filled heart is a one-way door
A heart laid in as solid black reads as grief, as a closed door, or as pure graphic mark depending entirely on the person wearing it, and we don’t ask which. Two practical notes anyway. Solid black needs even saturation or it heals patchy, and patchy black is among the hardest things in tattooing to correct. And nothing goes on top of it later — you can cover almost anything with black, but you can’t cover black. Pick it because you want it, not because it looks like the simple option.
Uneven lobes are the failure nobody sees coming
Symbol hearts fail in one predictable way: the two upper lobes come out unequal, or the point drifts off vertical. Neither is obvious on paper at full size, and both are glaring on a bicep at three inches, because the eye reads a heart as a symmetrical sign and flags any deviation instantly. Ask for the stencil to be checked in a mirror before it goes down. It costs a minute and it’s the most useful thing you can request in the whole appointment.
Narrowing it down
“A heart” splits in two before it splits into twelve.
Symbol or organ is the fork, and everything downstream depends on which side of it you land. After that the choice is which tradition — flash, devotional, anatomical, graphic — and only then how big and where. Five questions, in order. Answer the fifth first and you’ll end up choosing a design your budget can’t hold.
Symbol, organ, or devotional?
A traditional red heart, an anatomical heart, a Sacred Heart, a heart-and-dagger — these are genuinely different tattoos. The first question in every heart consultation is which heart, specifically. The symbol splits into at least six major traditions, and each carries different scale and style expectations.
Love, grief, faith, or survival?
Love, loss, faith, survival, allegiance, or plain aesthetic. A heart can carry any of these, but it has to be built around one primary reading. A heart that tries to carry love-and-memorial-and-faith at once reads as decoration with instructions.
Single heart or composed?
A solo heart is one design problem. A heart plus something else — a banner with a name, a dagger, a rose, a lock and key, a crown, a second heart — is another. A banner sets a minimum size on its own, because lettering has a floor. Settle the additions before the style, not after.
Traditional lineage or modern style?
Sailor-Jerry Traditional and Neo-Traditional hearts sit in one lineage — thick outline, flat red, white highlight. Fine line, single-needle, and contemporary illustrative hearts sit in another. The flash heart is a sign laid down with confidence. The fine-line heart is a contour drawn slowly. Those are different habits of hand, and most artists are genuinely good at one of them.
How big can you realistically commit?
A tiny fine-line heart is one hour. A full Sacred Heart composition with flame, thorns, and banner is four to six. Know your ceiling before you pick a design — scale determines which directions work and which compress into a smudge.
A heart is a category. Traditional, anatomical, Sacred, dagger, flame, lock — those are the designs.
The Traditional red heart has been tattooed continuously for a century. It got there on merit.
Partner-name hearts are the most common cover-up request in any working shop. Build the heart so it still works without the banner.
Twelve hearts
Twelve hearts, and the two families they split between.
A Traditional red heart on a bicep and an anatomical heart on a ribcage are not the same tattoo at different sizes. One is a sign; the other is a portrait of an object. Six of the twelve below descend from flash, four from devotional or medical illustration, and two are recent. Roughly in the order people ask for them.
The traditional red heart
Sailor Jerry canon
Bold black outline, flat red fill, white highlight, sometimes yellow rays behind. The most-stencilled heart in American tattooing for a century. Ages better than almost any other tattoo subject because the outline holds as the red drifts. 2–4 inches. Bicep, outer forearm, chest. The default for a reason.
The anatomical heart
Four chambers, aorta, vena cava
The medical-illustration heart — ventricles, atria, visible aortic arch. Often chosen by medical professionals, anatomy students, and survivors of cardiac events. Illustrative or realism style. Needs 4–6 inches to hold the detail. Upper arm, ribcage, outer thigh. Reads as precision rather than sentiment.
The Sacred Heart
Flame, thorn crown, banner
A Catholic devotional composition — anatomical heart ringed with thorns, topped with flame, often with a cross or banner. Traditional or Neo-Traditional style. 5–8 inches because every element needs room to read. Chest, bicep, upper arm. See the Sacred Heart ideas page for the full catalog.
The heart-and-dagger
Flash-book staple
A dagger piercing the heart, often with a single drop of blood, often with a banner carrying a name or the word “Mother.” One of the oldest compositions in American flash tattooing. Traditional style. 4–6 inches. Forearm, bicep, calf. Reads as heartbreak, betrayal, or the wound-you-survived.
The flaming heart
Passion and devotion
A traditional heart crowned with flame — often rendered yellow and orange at the top, solid red below. Carries religious, romantic, and punk readings interchangeably. Traditional or Neo-Traditional style. 3–5 inches. Bicep, forearm, chest. The flame adds about an inch of vertical length to the composition.
The locked heart
Lock, sometimes key
A traditional or neo-traditional heart with a keyhole or padlock integrated — sometimes paired with a matching key on another person. Reads as fidelity, protection, or the heart that belongs to someone specific. 3–5 inches. Inner forearm, chest, outer bicep.
The tiny fine-line heart
The smallest version that reads
A 0.5–1.5 inch fine-line or single-needle heart outline, often paired with a name, a date, or a small letter. The most-requested first tattoo in LA fine-line shops. Inner wrist, behind the ear, ankle, finger. Softens faster than larger work — plan for a touch-up at seven to ten years.
The heart-and-banner
The memorial classic
A traditional heart with a banner flowing across or beneath carrying a name or date. The oldest American memorial tattoo after the name-on-the-arm. Traditional or Neo-Traditional style. 4–6 inches to hold the lettering cleanly. Bicep, chest, outer forearm. Wait at least a year after the loss.
The crowned heart
Claddagh and beyond
A heart topped with a crown, often flanked by hands (the Claddagh, Ireland’s fidelity-friendship-love symbol). Traditional style, though illustrative versions carry well. 4–6 inches. Forearm, chest, upper arm. Read the crown carefully — some renderings carry royalist or gang associations in specific contexts.
The split or two-piece heart
Matching composition
A single heart rendered as two halves, one on each partner, friend, or sibling. When joined, the pieces complete each other. Traditional or fine-line style. 1.5–3 inches each. Same-artist same-day same-stencil rule applies absolutely — matching across shops destroys the composition. See matching notes below.
The bleeding heart
Grief made literal
A traditional heart with one, three, or more drops of blood falling from the bottom curve. Reads as unhealed grief, as active mourning, as the piece a client gets while the loss is still loud. Traditional or Neo-Traditional. 3–5 inches. Bicep, chest, upper arm. The style carries the weight.
The black heart
Ignorant, blackwork, or solid-fill
A traditional heart silhouette filled solid black, or rendered in the intentionally rough ignorant-style outline with no fill. Reads as defiance, as grief without softness, as the aesthetic rejection of the red-heart style. 2–4 inches. Outer forearm, bicep, chest. Cross-link: blackwork style.
Five placement styles
The placement everybody asks for, and four that work better.
Chest-over-the-heart is the first thing people say and it isn’t always the right answer: the skin there moves, the placement forces a scale, and the literalism can flatten a design that would have carried more elsewhere. Five placements cover nearly every heart that gets stencilled here.
Bicep and outer forearm — the flash placement
Bicep · outer forearm · chest · calf
The traditional placement and the traditional style. A red heart on the bicep is one of the most-tattooed compositions in American history. Reads as statement, reads at six feet, reads as the style inherited from every sailor, trucker, and grandmother who came before.
Shoulder blade and hip — the heart worn quietly
Shoulder blade · upper back · hip · inner bicep
The heart reads as ornament against a curve. No era-shorthand. Works for neo-traditional, illustrative, and fine-line styles equally. Often chosen for hearts that carry private meaning without public announcement.
Inner forearm and sternum — no style era attached
Inner forearm · ribcage · sternum · inside wrist
These placements read as “heart tattoo” without locking in a style-era. Inner forearm and ribcage are the two most-requested modern heart placements. Fine line and single-needle belong here.
Inner bicep and ribs — the heart nobody asks about
Sternum · underboob · inner thigh · behind ear · nape of neck
Private style — a tattoo for the wearer. Often paired with fine-line or single-needle because the scale and the intimacy match. The heart that lives mostly inside the wearer’s own eyeline.
Chest panels — where the Sacred Heart actually belongs
Full chest · center chest over heart · ribcage panel · back panel
A Sacred Heart chest piece, an anatomical heart over the sternum, a full memorial composition in the rib-to-hip zone. Planned from day one, executed across three or more sessions. The style where a heart becomes the anchor of a larger piece.
Six styles
Six styles, and what each one does to a heart.
Each heart has styles that serve it and styles that fight it. Pick the wrong one for your scale and placement, and you end up with a tattoo that ages against you.
American Traditional — flat red, bold line, white highlight
Sailor Jerry flash lineage
Bold 3/0-liner outline, flat red fill, white highlight, yellow rays. The heart that has been tattooed continuously for more than a century and still reads at year forty. If you want longevity, this is the style. Never been tattooed and want a heart? Traditional is the default for a reason.
Neo-Traditional — ornament built around the shape
Expanded palette, dimensional bones
Burgundy, dusty rose, muted gold, sage — plus dimensional shading on the heart muscle. Where most mid-scale heart work lives in 2026, because neo-traditional gives you ornament and color without asking you to commit to photorealism. Two sessions is common for anything over five inches.
Fine line — the two-stroke heart, and where it thins
The dominant 2020s style
Hairline work, minimal shading, often black-only. The most-requested style in LA for small hearts. Softens faster than bold lines — plan for a touch-up at seven to ten years. Best on stable-skin placements (forearm, ribcage, chest). Struggles on fingers and knuckles.
Black-and-gray realism — the anatomical heart’s home
Anatomical and Sacred Heart work
Full tonal shading, photographic rendering. Where anatomical hearts and detailed Sacred Heart compositions earn their keep. Doesn’t scale down — 5 inches is the floor. Bring reference if you want a specific heart (your own cardiac image, a particular devotional icon).
Etched line — medical plate and devotional engraving
Line-first, etching style
Deliberate line-weight variation, crosshatched shading, the look of a pen-and-ink drawing. Keeps its structure for decades because every value in it is carried by a line rather than a wash. Pulls from Victorian medical illustration for anatomical hearts, devotional plate art for Sacred Hearts.
Solid blackwork — the filled heart, and its one-way door
Solid fill or intentional rough line
The black heart silhouette, or the rough wobble-line ignorant heart. Reads as intentional aesthetic rather than technical aspiration. Ages predictably because the mark is built on black saturation rather than colored pigment. Best for small hearts on outer arm, bicep, calf.
The lobe-and-point problem
How small before a heart stops reading as a heart?
Smaller than most subjects, as it turns out, because a symbol heart survives on two curves and a point. The organ is the opposite problem and has a hard floor. Four tiers.
A flat red heart at day one tells you nothing. Ask what the red looks like at year eight.
Memorial hearts should wait. Grief moves faster than the tattoo does.
If it’s your first heart, flat red and a bold outline is the honest answer. That combination has forty years of evidence behind it.
Eight things added to a heart
Eight additions, and what each one claims about the heart underneath.
A bare heart says almost nothing, which is why the flash tradition almost never left one bare. Every addition below is a claim: pierced, crowned, locked, burning, named. Pick the claim before you pick the ornament.
Heart + banner
The oldest memorial composition in American tattooing. A traditional heart with a banner carrying a name, date, or word. Traditional or neo-traditional style. Bicep, chest, forearm. Ages as well as the lettering does.
Heart + dagger
Heartbreak, betrayal, or the wound you survived. Flash-book staple. Traditional style, 4–6 inches. Cross-link: dagger ideas.
Heart + rose
The Valentine’s style. Oldest rose-pairing in American flash. Small, loud, honest. Traditional, 3–5 inches. Cross-link: rose ideas.
Heart + crown
The Claddagh echo. Traditional heart topped with a crown, sometimes flanked by hands. Forearm, chest, upper arm. Traditional or illustrative style.
Heart + lock and key
Fidelity or commitment composition. Often split across two people — one wears the heart with keyhole, the other wears the key. Fine-line or traditional. 3–5 inches. Same-artist same-day same-stencil rule.
Heart + thorn crown (Sacred Heart)
Catholic devotional composition. The full Sacred Heart reading — anatomical heart ringed with thorns, topped with flame. 5–8 inches. See sacred heart ideas for the full catalog.
Heart + flame
Passion, devotion, or the heart that refuses to quit burning. Often paired with the Sacred Heart but works as a standalone composition. Traditional or neo-traditional. 3–5 inches.
Heart + arrow (pierced)
The Cupid style — a single arrow through the heart, often with feathers showing at one side. Traditional or neo-traditional. 3–5 inches. Bicep, forearm, chest. Valentine’s classic.
Where heart work fails
Eight ways a heart disappoints the person wearing it.
Nearly every heart we are asked to fix or cover went wrong in one of these eight places, and the majority went wrong at the stencil rather than at the needle.
Thirty saved images, one compromise
Thirty saved images, bits picked from each, artist asked to combine. Result: a heart that belongs to no specific designer. Fix: three references, and for each one say the single thing you want from it. That lobe curve. That banner shape. That weight of black.
Sacred Heart detail at half an inch
Wanting a full Sacred Heart with thorns and flame at 2 inches. The detail doesn’t fit — blurs within five years. Fix: if you want the composition, commit to the scale. Five inches is the floor for Sacred Heart.
The partner-name trap
A heart wrapping a partner’s name, booked at month three of the relationship. Fix: build the heart so it works as a solo composition if the name ever needs to go. Not cynicism — design hygiene.
Fine line on a knuckle
Fine-line heart on a knuckle. Traditional red heart at 0.5 inches. Full Sacred Heart on a wrist. Each heart style has a scale and a placement that punish it. Fix: ask the artist which placements their version of this category has held at ten-year marks.
The matching-drift trap
Two people, two shops, two months apart, “same heart.” They will drift in outline weight, color, and curve. Fix: same artist, same day, same stencil. Matching hearts are their own design problem.
The memorial heart at month three
Booking a memorial heart within six months of the loss. Grief keeps moving. Fix: wait at least a year. The piece you need at month four is rarely the piece you need at year two.
The generic-heart default
Picking a heart by reflex — the first shape that comes to mind, no meaning behind the choice. Result: a heart that reads as decoration. Fix: a heart chosen on purpose reads as yours. Name what it marks in one sentence before you pick the design.
Choosing from the shiny-wrap photo
Choosing an artist from shiny-wrap Instagram. Flat red photographs at its absolute best in the twenty minutes after it’s wrapped. Fix: ask that artist for a red heart at one year and another at five. That’s the tattoo you’re buying.
Before the consult
Six answers that save the first hour.
Settle these before you sit down and the first drawing arrives close. Arrive without them and the first hour goes to ruling things out.
Which of the twelve, by name?
Traditional red, anatomical, Sacred Heart, heart-and-dagger, flaming, tiny fine-line, locked, crowned, memorial-with-banner, split, bleeding, or black. These are twelve different tattoos. Pick the species first.
What’s it marking?
Love, loss, faith, survival, allegiance, beauty. Pick one primary. A heart can carry more than one reading but has to be built around the one that matters most.
Single or composed?
A solo heart is one design problem. A heart with a banner, dagger, rose, lock, crown, flame, or second heart is another. Lettering in particular sets a floor size on its own.
Traditional or modern style?
Sailor-Jerry lineage, or fine-line / illustrative lineage? These are different visual languages. Traditional ages the most predictably. Fine line softens faster but carries the contemporary LA style most cleanly.
Chest, or somewhere less literal?
Bold (bicep, forearm), classical (shoulder blade), modern (inner forearm, ribcage), intimate (sternum, inner bicep), or statement (chest piece, back panel). Match placement to what the piece is for.
What scale?
A 1.5-inch fine-line heart is a single hour. A 6-inch Sacred Heart is three to five. A chest piece with thorns, flame, and banner is three to five sessions. Know your ceiling.
The first-heart guide
If this is your first one, Traditional is the honest answer.
Flat red, bold outline, three inches, outer arm. Eight decisions the first heart should make deliberately rather than by default.
Personalization
The shape, the one addition, and the thing you never explain.
A heart becomes yours in three layers, and they carry very different weight. Almost everyone arrives having decided the first and having never considered the third, which is the layer that keeps a shape everybody recognizes from reading as a sticker.
Bones: shape, style, scale, placement
Style, size, placement, palette. These are the bones — whether the piece reads as Traditional, Neo-Traditional, fine-line, anatomical, or Sacred Heart, and whether it reads as bold, classical, modern, or intimate. Most clients stop here.
The one addition that makes it yours
A specific banner word (Mom, a child’s name, a date). A color tied to a story. A specific anatomical reference (your own cardiac image, a specific devotional icon). A companion element — a single rose, a particular dagger. This is where the piece starts separating from the category.
The part you never explain
The reason. Nobody is owed it, including the artist. The private layer is what keeps the piece from ever reading as generic — even if it reads as a standard heart to strangers, you carry what’s underneath.
Matching heart tattoos
Two hearts is the most-booked matching request in any shop.
A matching heart has to keep working if the other person stops speaking to you. That gets designed in at the stencil or it doesn’t happen at all.
Couples, sisters, and the best-friend pair
Couples most commonly, then siblings, then close friends, occasionally parent-and-adult-child. Different relationships invite different compositions — the split heart for partners, matching traditional hearts for friends, anatomical hearts for the medical-professional family pair.
Match the heart, vary the detail
Same base design, small variation per person — different banner word, different color accent, different placement. Each piece still belongs to the person wearing it while the composition remains shared.
Build it so the banner can come off
Especially for couples. If a breakup or a death would destroy the piece, redesign it now so it works as a solo composition too. That isn’t cynicism. It’s the same care you’d give any other permanent thing two people bought on the same afternoon.
One hand, one stencil, one afternoon
The only way matching hearts actually match is if the execution is identical. Booking the same design with two different artists, two months apart, produces two hearts that look approximately similar rather than one matching pair.
FAQ
Eight questions that come up before a heart gets stencilled.
Eight questions covering meaning, aging, first-tattoo guidance, scale, Sacred Heart versus plain heart, pricing, matching tattoos, and the heart-and-dagger composition.
What does a heart tattoo mean?
A heart tattoo can carry six distinct readings, and the design has to be built around one primary. Love is the default — romantic love, parental love, the kind of love that sends someone to a shop for a Valentine. Loss is the memorial style, usually paired with a banner carrying a name or date. Faith is the Sacred Heart and related devotional compositions. Survival is the anatomical heart worn by cardiac patients or the bleeding heart worn during unresolved grief. Allegiance is the heart-and-banner with a loved one’s name, or the Claddagh’s friendship style. And sometimes it is plain aesthetic — a traditional flash heart carried for the look of American tattooing itself. The honest starting question: which of those six is the heart for you?
Which heart tattoo ages the best?
American Traditional, without contest. Bold outline plus flat red plus white highlight scaffolds the piece against decades of skin drift — a well-laid Traditional heart at age 25 still reads as a Traditional heart at age 55. Neo-Traditional ages moderately well because the outline scaffolds the expanded palette. Fine-line and single-needle hearts soften faster because the hairline weight is at the limit of what skin holds; plan for a touch-up at seven to ten years. Anatomical and realism hearts age well on stable-skin placements (outer thigh, ribcage, chest) and poorly on high-flex zones. If you want a heart that looks right in 2060, pick Traditional and commit to the bolder outline that style asks for.
What’s the best heart tattoo for a first tattoo?
American Traditional at 2–3 inches on the forearm or outer bicep, or a fine-line outline heart at 0.5–1.5 inches on the inner wrist or behind the shoulder. The first carries the strongest century of aging evidence; the second carries the strongest current LA style. Plan on one to two hours in the chair, one session, pricing discussed at consultation. Book with an artist whose HEALED portfolio at one-year-plus is documented, not just their fresh-wrap Instagram feed. For a first heart, boring ages well — and there is nothing wrong with the most-tattooed subject in American history.
How big should a heart tattoo be?
Depends on which heart. Fine-line outline: 0.5–1.5 inches works, anything larger loses the style. Traditional red heart: 2–4 inches is the sweet spot, smaller than that and the white highlight compresses. Anatomical heart: 4–6 inches minimum because the chamber detail needs room. Sacred Heart: 5–8 inches minimum because thorn crown, flame, and banner each need their own real estate. Heart-and-banner memorial: 4–6 inches to hold the letterforms cleanly. The honest rule: your heart species sets your scale. If you want the full composition, commit to the size it asks for.
What’s the difference between a Sacred Heart tattoo and a heart tattoo?
A Sacred Heart is a specific Catholic devotional composition — anatomical heart ringed with thorns, topped with flame, often with a cross or banner, sometimes with blood drops at the base. It carries explicit religious meaning tied to Jesus’s love and suffering. A plain heart tattoo (the traditional red silhouette, the anatomical drawing, the fine-line outline) has no required religious content; its reading is whatever the wearer brings. If the piece is a devotional tattoo, say so at the consultation and the artist will build a full Sacred Heart composition. If the reading is love, loss, or aesthetic, a plain heart with or without banner and flame is the cleaner choice. The two are not interchangeable — the Sacred Heart carries the tradition explicitly.
How much does a heart tattoo cost in LA?
Heart pricing at Apollo scales with four factors: overall scale, style complexity, color versus black-and-gray, and session count. A small fine-line outline or traditional red heart is typically a single session at one to three inches. A mid-scale neo-traditional flaming heart or heart-and-banner usually spans one to two sessions. Sacred Heart compositions with thorns, flame, and banner run two to four sessions. Full chest-piece heart anchors planned from day one run four or more sessions. Hourly is $100 with Blue, Hannah or Rick and $350 with Raa or David, and the number moves with artist, size, design and placement. We quote off the drawing, not the description.
Should I get a matching heart tattoo with a partner?
It depends on the relationship stability and the design approach. Matching heart tattoos are one of the most-requested appointments in any working shop and one of the most under-planned. Working rules: match the heart, vary the detail (different banner word, different color, different placement so each piece still belongs to the wearer); plan for the piece to outlive the relationship — if a breakup would destroy the design, redesign it so it works as a solo heart; book the same artist, same day, same stencil, because matching across studios drifts in line weight, red saturation, and proportion. Not every matching piece needs to survive every relationship — but it should survive the decision you’d make today, without you.
What does a heart-and-dagger tattoo mean?
Heartbreak, betrayal, the wound you survived, or the flash-canon aesthetic inherited from a century of American tattooing. The composition is one of the oldest in Western tattoo flash — a dagger piercing a traditional red heart, often with a drop of blood, often with a banner carrying a name (frequently “Mother” in the earliest versions). It can read as grief (the wound that shaped you), as warning (the heart that will not be taken again without a fight), or as pure Traditional-style nostalgia for clients who wear flash for its own sake. The reading is carried by what the wearer brings; the composition is flexible enough to hold any of the three.
Symbol or organ. Then the other eleven questions
Know which heart you mean before you know how big it is.
Symbolic or anatomical? That single question splits the appointment two ways and it is worth deciding before you sit down. Banners, daggers, crowns and thorns are all downstream of it.
