# Rays behind a sacred heart, open at the sides

> Straight gold rays back a sacred heart, cut short at the sides so the shape never closes into a disc — the difference between a print and a badge.

A heart, wrapped once in a ring of thorns, a small flame sitting where a candle wick would be.
Behind it, straight gold rays reach out — long above and below, pulled in short at either side, so
the whole shape never quite closes into a ring.

That shortening looks like the artist ran out of room. It's the opposite: it's the one decision
holding the whole print together.

## What is this design?

The sacred heart, drawn the way flash has drawn it for as long as flash has existed: a heart bound
in thorns, one flame on top, sitting inside a burst of straight rays. None of the parts are
invented for this shirt — thorns, flame and rays are the standard kit, put together the way
they've always been put together.

The other classics solve the same problem, filling a bare chest, differently. [A blade driven
straight through a rose](/stories/dagger-through-a-rose) fills the space with overlap instead
of a backing shape. Here the answer is rays, and what isn't standard is left to the artist every
time: how long they run, and where they stop.

## Why do the rays stop short at the sides?

Because run at one length all the way round, they stop being rays and start being a disc.

A ray is a straight line reaching out from a centre. Draw a full ring of them at the same length
and the tips line up into an implied circle, whether or not anyone draws the connecting arc — the
eye finishes it for you. Once that circle closes, the print starts behaving like a badge: a seal, a
coin, a patch waiting for a pin backing.

It's the same logic that keeps [a banner arcing overhead from curling back into a ring at either
end](/stories/script-banner-open-arc) — anything meant to sit on a chest, rather than replace
one, has to leave the sides alone.

## How much of the chest should the rays fill?

Enough to read as a burst from across a room, not enough to reach the seams.

Short rays that stop well inside the shoulders leave a print with edges — cloth on either side of
the design, the way a chest print normally sits. Extend them far enough to touch the sides and
you're back at the closed-loop problem from a different direction: a burst that reaches the seams
starts to behave like a wrap rather than a print sitting on a shirt.

## Do I need permission to use a sacred heart?

No. It's devotional art that flash absorbed generations ago, and a century of tattooers redrawing
it slightly differently each time has left no single version belonging to anyone in particular.

What's licensable is a specific artist's specific rendering — a named flash sheet, a particular set
of proportions somebody actually signed. The heart, the thorns, the flame and the rays are the
pattern everyone draws from, so nobody can hand you permission for those on their own.

## Does the ray backing only work behind a heart?

No — rays are a mechanism, and the heart is one thing you can put in front of them.

A name, a portrait outline, a different traditional subject: swap what sits at the centre and the
rule about the sides doesn't change. For a chest with no drawn subject in front of it at all,
[a solid panel with shapes cut clean out of it](/stories/blackwork-cut-out-panel) does the same
job of filling the space without ever closing a loop, by a completely different method.

## Won't a heart and thorns read as religious?

For some people, and that's a real reason to choose it — the sacred heart is devotional art, and
wearing one is a legible way to wear a faith.

For a lot of chests it reads differently. A century of flash use has pulled the image off the altar
and onto the same shelf as the swallow and the dagger, so on plenty of people it just reads as
tattoo grammar rather than a statement of belief. Both readings are available, and it's worth
knowing which one you're choosing rather than assuming the second.

## Does it print well?

Yes, in flat gold, cream and black — three colours with hard edges, which is what this design has
always been drawn in.

The rays are thin flat shapes and survive printing easily as long as they're not drawn hairline
thin. The flame is the one part with real detail — a few licking points at the top — and it prints
better simplified rather than rendered fussily, since fine flicks at that size are exactly what the
weave eats first. Oxblood behind the gold gives the ray colour somewhere to actually show up.

## How do I get one made?

Describe the subject at [JustOG](/) and specify a sacred heart with rays behind it, thorns and
however many flames you want. Pick a direction, drag the crop frame, see it composited on the real
garment, and it's made to order and shipped.

Twelve rays reaching out, and the two shortest ones are doing most of the work.
