Designing a unit patch that still works in thread

A design that looks right on a laptop at full screen frequently does not read at three inches across a shoulder. Here is how to design for the real size.

Design at the size it will be

The single most useful habit. Set your canvas to the actual finished size — 3 inches, or 3.5 — and look at it at 100%, printed if you can.

Almost every problem on this page becomes obvious immediately when you do that, and invisible when you design zoomed in.

Rules that hold up

Fewer colours than you think. Every colour is a thread change. Three to five reads cleanly and looks deliberate. Ten looks muddy at three inches, because adjacent colours stop being distinguishable at that scale.

Contrast between neighbours. Two mid-tones side by side merge into one shape from arm’s length. Test by converting to greyscale: if the shapes disappear, they will disappear in thread too.

Uppercase for small text. Capitals hold their form at sizes where lowercase fills in. Keep any lettering at a quarter inch tall or more.

Fewer words. A motto is a motto because it is short. A full sentence around a border ends up illegible, and the sentence was never the point.

Bold shapes over fine detail. If the design would read as a stencil, it will read as a patch.

Layout that suits the shape

Most patches are a conventional outline — circle, shield, rectangle, tab — because that is what a merrowed border can wrap. Design into that shape rather than fitting a square design inside it afterwards.

A circle wants a central device with text curved around the perimeter. A shield wants a strong vertical axis. A tab wants one or two words and nothing else.

Leave a margin. The border consumes a few millimetres all round, and artwork running to the very edge gets clipped by it.

Heraldry and inherited crests

Unit crests usually arrive as a scan of something drawn decades ago for print, and print permits detail thread does not.

Expect to lose fine hatching, thin scrollwork and small mottos. What matters is that the recognisable elements survive — the device, the colours, the overall silhouette. Somebody who knows the crest should recognise it instantly at three inches, which is a different goal from reproducing every line.

We redraw for thread and show you exactly what was simplified on the proof, so this is a conversation rather than a surprise.

Things worth deciding before you order

• Size. 2 to 5 inches on the longest edge. Most land at 3 or 3.5.
• Shape, and whether it needs a merrowed or laser-cut edge.
• Backing — hook-and-loop, sew-on, iron-on. See the backing guide.
• Construction — thread or PVC, which mostly comes down to how much detail you need.

Get agreement before the proof, not after

If the design has to satisfy a group, settle it among yourselves before it reaches us. Production starts when the proof is approved, so a design still being argued about is a delivery date still moving.

The proof is the last checkpoint, and it is a real one: nothing is manufactured until someone approves it, and if the patches do not match what was approved, we remake or refund.

You do not need a designer

A photo of a sketch is a perfectly good starting point. The digitising step redraws it either way. What a designer buys you is fewer surprises at the proof — not permission to order.
