What you need
- The patch (sew-on, or iron-on if you plan to iron and then stitch) - A sharp hand-sewing needle; a denim needle for heavy denim; a leather needle for leather - Polyester thread in the colour of the patch border (or clear nylon thread for an invisible finish) - Pins, a few strips of masking tape, or fabric glue stick to hold the patch - A thimble for denim and leather - Small scissors
Polyester thread is stronger than cotton and does not rot or shrink in the wash, which is why it is the standard for patches.
How to sew a patch on by hand
- Decide on placement. Try the jacket on and mark the spot with tape. Our patch placement guide gives standard positions for chest, sleeve and back.
- Pin or tape the patch in place. On leather, use tape or clips instead of pins, because pin holes stay visible.
- Cut about 60 cm of thread, thread the needle and tie a knot at one end. Use a double thread for heavy jackets.
- Start from the inside of the jacket and push the needle up through the fabric just inside the patch border, so the knot is hidden.
- Sew a whip stitch: bring the needle over the border and down through the jacket just outside the edge, then up again 3 to 4 mm along. Work all the way round.
- Keep your free hand, a wooden spoon or a piece of card inside the sleeve or body so you do not stitch through both layers.
- When you return to the start, push the needle to the inside, make two or three small stitches in the same spot and tie a secure knot.
- Trim the thread and check the edges are flat with no gaps.
For a less visible finish, use a running stitch just inside the border, through the patch itself, instead of over the edge.
How to sew a patch on with a sewing machine
A machine is faster and gives a neat line, but sleeves and backs are awkward to reach.

GET A FREE MOCKUP- Fit a denim or jeans needle (size 90/14 or 100/16) for jackets.
- Thread the machine with polyester thread matching the border on top and the jacket colour in the bobbin.
- Set a straight stitch of about 2.5 to 3 mm, or a narrow zigzag that just catches the border.
- Pin or iron the patch in place.
- Sew slowly around the inside edge of the border, pivoting at corners with the needle down.
- Overlap the first few stitches at the end and back-tack.
For sleeves, open the sleeve seam or use a machine with a free arm. If that is not possible, sew sleeve patches by hand.
Sewing patches onto different jacket fabrics
| Jacket | Needle | Tips |
|---|---|---|
| Denim | Denim needle, thimble | Iron-on plus edge stitching gives the strongest hold |
| Leather and suede | Leather needle (wedge point) | Longer stitches (5–6 mm); never iron; tape instead of pins |
| Wool (varsity, peacoat) | Sharp, medium needle | Use a whip stitch so the stitch sinks into the wool; no ironing |
| Nylon and waterproof | Fine sharp needle | Stitch as few holes as possible and seal them with seam sealer inside |
| Fleece | Medium needle | Do not iron; pin generously as fleece stretches |
| Canvas and work jackets | Heavy needle, thimble | Use double thread for durability |
Sewing patches on leather biker vests
Leather vests are the traditional home of club patches and are heavy to sew. Use a leather needle, strong waxed polyester thread and stitches about 5 to 6 mm apart, and take your time on large back patches. Many riders ask a cobbler or leather repairer to machine-stitch large back patches. Our guide to biker and motorcycle club patches covers layout and rockers.
How to stop the patch moving while you sew
Patches slide on slippery fabric. Three ways to stop it:

GET A FREE MOCKUP- Order iron-on backing and press the patch in place first (cotton and denim only).
- Use a fabric glue stick on the back of the patch, then let it dry.
- Tack it in four places with large stitches before sewing the border, then remove the tacking.
Iron-on or sew-on?
If you have not ordered yet, see iron-on vs sew-on patches. For jackets, the strongest result comes from iron-on backing plus edge stitching on denim and cotton, and sew-on backing on everything else. Irish Customized Patches makes embroidered, leather and biker patches with either backing.
What this guide is based on
These are the sewing instructions we give customers who order sew-on patches from Irish Customized Patches. Needle sizes and stitch lengths are typical starting points; test on a hidden seam first if you are unsure about your fabric. Get a free mockup for your jacket patches.
