How to make embroidered patches with a home embroidery machine

Most patches fall between 50 and 100 mm (2 to 4 in) across. That range fits a 4 × 4 in (100 × 100 mm) hoop, sits well on a jacket sleeve, cap side, backpack or chest, and is large enough for a short line of text.

Common sizes:

• 50–65 mm (2–2.5 in): sleeve and cap patches, simple icons, one or two words at most.
• 75–90 mm (3–3.5 in): the classic badge size for jackets, bags and uniforms.
• 100 mm (4 in) and up: detailed scenes, club logos with a ring of text, back-of-jacket statements (a jacket back design is usually closer to 250 mm).

Design for the size you will actually sew. Embroidery thread has a fixed thickness, so detail does not shrink the way pixels do:

• Keep letters at least 5 mm tall for capitals with satin columns, and closer to 7 mm on a patch where the text sits on a textured twill. Thin serif details and lowercase letters under that height fill in or break up.
• Leave a gap of 1–2 mm between the border and any text or detail that runs along it, so the border doesn't swallow it.
• Use few colours and large shapes. A 60 mm patch with ten colours and fine shading reads as noise from a metre away.
• Keep background areas unstitched where you can. The twill already gives you the background colour, and skipping a full background fill saves thousands of stitches and keeps the patch flexible.

A satin patch border is usually between 1.5 mm and 3 mm wide on a home machine, and wider (3–5 mm) when the edge will be cut after stitching with a hot knife or scissors, because a wider border leaves more room for error.

The border has two jobs: it covers the raw cut edge so it can't fray, and it gives the patch its finished outline. To do the first job, it must be stitched so that it straddles the cut edge, with most of the column on the fabric and the outer swing of the needle dropping just past the edge, into the stabilizer. If the needle never goes over the edge, fibres poke out; if it goes too far, the outside of the border has nothing to hold it and the stitches can roll off.

Practical guidance:

• 1.5 mm: fine for small, simple patches trimmed carefully in the hoop. StitchMyPic's Patch style uses 1.5 mm by default, and you can widen it in the border options.
• 2–3 mm: a safer, more traditional patch look, and more forgiving if your trimming is not perfectly close.
• 3–5 mm: for patches cut out after sewing, where you need a wide band to cut against without slicing into the stitches.

Use a full, dense satin with an underlay (an edge run plus a zigzag) so the border stands up and hides the fabric. If you see a gap between the fill and the border after sewing, the fill is pulling in: add pull compensation to the fill (a few tenths of a millimetre) or use a firmer stabilizer.

Merrow vs satin: commercial patches often have a merrowed edge, a rolled overlock stitch made on a dedicated merrow machine after the patch is cut out. It gives a thick, rope-like edge on round and simple shapes. A home embroidery machine can't make a merrow edge, but a dense satin border gives a clean, flat edge on any shape, including stars, letters and irregular outlines that a merrow machine can't follow.

In StitchMyPic's border options you can choose how the border follows the design: around the design outline, around every edge, or as a rectangle, rounded rectangle or oval, with its own width, colour and gap, and with or without a fill inside.

The base fabric should be firm, tightly woven and not stretchy. Polyester twill is the standard for embroidered patches: it holds dense stitching, comes in many colours, and cuts cleanly. Other good choices:

• Patch twill or patch material: twill sold specifically for patches, often with a stiffer finish. Some products are made so that the cut edge looks finished enough for hot-knife cutting.
• Felt: easy to cut, doesn't fray, good for kids' and craft patches. Use a firm, dense felt; thin craft felt stretches and distorts under a dense fill.
• Canvas, denim, sailcloth: sturdy and fine for bags and workwear patches.
• Marine vinyl or faux leather: doesn't fray, but every needle hole is permanent, so use a lighter density.

Avoid knits and stretchy fabrics. They pull in as you stitch and the patch ends up wavy.

Stabilizer options:

• Heavy tear-away: the usual choice for trim-in-the-hoop. Tear it away carefully after sewing; a few stubs hidden under the border are normal and get covered by the backing. One heavy layer or two medium layers.
• Heavy water-soluble (fibrous, not film): dissolves completely so nothing shows on the edge. It is the cleanest finish for the border, but it can perforate unevenly under dense satin, so use a heavy grade, or two layers.
• Cut-away: gives a stiffer patch, but you must trim it very close to the border, which takes care.
• Crinoline: a stiff open-weave backing used by commercial patch makers alongside tear-away.

Use a sharp 75/11 embroidery needle and 40 wt polyester or rayon thread. Polyester is tougher for patches that go through the wash or onto bags.

This is the trim-in-the-hoop method for a DIY embroidered patch. Your file needs the colour stops in this order; well-made patch designs already sew the border last.

1. Hoop the stabilizer. Hoop heavy tear-away or heavy water-soluble stabilizer, drum tight and wrinkle-free. If you hoop the twill too, smooth it but don't stretch it, or the patch cups into a bowl when released.
2. Sew the placement line. A single running stitch on the bare stabilizer shows where the fabric goes. Skip this step if the fabric is hooped.
3. Lay the fabric over it. Cover the placement line with at least 10 mm of fabric to spare on every side. Hold it with temporary spray adhesive or tape outside the stitching area.
4. Sew the tack-down. A running stitch (or a light zigzag) just inside the placement line fixes the fabric. The machine should then stop.
5. Trim. Take the hoop off the machine without unhooping and cut the fabric close to the tack-down, about 1 mm away, with curved appliqué scissors (duckbill or double-curved). Don't cut the stabilizer. This trim decides how clean the border looks.
6. Sew the design. Put the hoop back and sew the fills, details and lettering.
7. Sew the satin border last. It covers the trimmed edge and the tack-down. Check that no fabric is peeking out on the outer side; if it is, trim and sew the border again.
8. Remove and finish. Tear away or rinse away the stabilizer, let the patch dry flat if it was washed, and clean up thread tails and loose fibres.

For several patches, tile copies in a larger hoop and group the colours, so all placement lines run first, then all tack-downs, then all fills and borders. You trim everything at one stop instead of several.

How you cut depends on when the fabric was cut.

• Trim-in-the-hoop: the fabric is already cut. You only remove the stabilizer. Tear-away comes off in small pieces; tear towards the border rather than away from it, and support the stitching with your thumb. Water-soluble stabilizer dissolves under running water.
• Cut after stitching (scissors): cut just outside the border, leaving a hair of stabilizer, never into the satin stitches.
• Hot knife: used on polyester patch twill embroidered as a whole sheet. The heated blade melts and seals the edge as it cuts. Work on a heat-proof surface such as tempered glass, hold the knife at an angle, use only the tip with even pressure, move slowly and wipe the blade clean every few centimetres. This only works on synthetic fabric and needs a wide border.
• Laser or die cutter: used for cutting batches of identical shapes before embroidery, in the cut-first method.

A quick pass with a lighter or heat tool can tidy polyester fuzz on the edge, but keep it moving: polyester thread melts fast and rayon scorches.

The backing decides how the patch attaches, how long it stays put and whether it can be moved. Pick it based on what the patch goes on and how often that item is washed.

Iron-on (heat-seal): a heat-activated adhesive film fused to the back of the patch. Commercial heat-seal films are applied with a heat press; for example, Madeira lists its 4220 nylon heat seal at medium pressure, 286–376 °F (about 141–191 °C), for 15 seconds. Home iron-on adhesive patch backing works too: Therm O Web's HeatnBond UltraHold instructions call for a medium, dry iron (no steam), 2 seconds per section to fuse the adhesive to the back, then 8 seconds of firm pressure per section to bond the patch to cotton, longer for thicker fabrics. UltraHold is a no-sew adhesive; if you also want to stitch around the patch, the maker recommends HeatnBond Lite instead. Heat seal on the back also locks the threads in place and covers any stabilizer stubs.

Sew-on: no backing, or a plain fabric backing. It is the most durable choice and the only good one for leather, nylon jackets and other fabrics that can't take heat.

Hook-and-loop: sew the hook side to the back of the patch and the loop side to the garment or bag. Common on uniforms, tactical bags and caps where patches are swapped.

Adhesive (peel-and-stick): a pressure-sensitive adhesive for temporary use on hard surfaces, bags or event badges. It won't survive washing.

Many embroiderers combine two: an iron-on backing to place the patch exactly, then a line of stitching around the border so the edges never lift in the wash.

Ironing on: pre-wash the garment without fabric softener, which can stop adhesives from bonding. Position the patch, cover it with a pressing cloth or baking paper, and press with firm pressure (don't slide the iron) for the time on your adhesive's instructions. Turn the garment inside out and press from the back as well. Let it cool completely before you test the edge. Avoid ironing over the area repeatedly afterwards.

Sewing on: pin or fuse the patch in place, then sew right next to the inside edge of the satin border with a straight stitch, or with a narrow zigzag over the border in a matching thread. Use a denim or leather needle for heavy fabrics. By hand, a whip stitch over the border with matching thread works well.

Hook-and-loop: cut the loop side slightly smaller than the patch so it doesn't show, and sew it to the garment first. Sew or glue the hook side to the back of the patch.

Wash patched garments inside out on a gentle cycle, and dry on low heat or hang to dry. That is easy on both the adhesive and the satin edge.
