Pin or tape the patch in place, then stitch around the edge with a whipstitch, an over-the-edge stitch, using a strong needle and heavy-duty thread. Keep stitches small and evenly spaced, just inside the patch border. By machine, use a zigzag or straight stitch with a sturdy needle and go slowly around the edge. Sew-on is the most durable way to attach a patch and it survives repeated washing.
A note on the specifics below: the stitch, needle, and thread choices here are widely used, but the best combination depends on your patch thickness and the item you are sewing onto. Match the needle and thread to the job, and test on a scrap or hidden area where you can.
What you will need
- Thread: strong thread is the standard for patches. Heavy-duty polyester or nylon is a common choice for thick embroidered patches. Match the color to the border to hide the stitches, or contrast it on purpose.
- Hand needle: a sturdy sharp, embroidery, or leather needle that can pass through a thick border without bending. A thimble helps.
- Machine needle: a heavier size is easier on dense patches. A 90/14 is a common starting point, but match the needle type and size to both the garment and the patch thickness.
- Straight pins or fabric tape, and small scissors
How to sew a patch on by hand
- Position and secure. Place the patch and pin or tape it so it cannot shift. This is also your last chance to check placement.
- Thread and knot. Cut about 18 inches of thread, thread the needle, and knot the end. Doubling the thread adds strength.
- Come up from behind. Bring the needle up from the inside so the knot hides under the patch, exiting just at the patch edge.
- Whipstitch around the edge. The whipstitch, a small diagonal stitch that wraps over the patch edge, is the classic patch stitch because it hugs the border and resists lifting. Keep stitches close and even. For high-stress spots, a backstitch or a triple straight stitch adds reinforcement.
- Finish off. Knot the thread on the inside and trim. Avoid stitching across seams and pockets where the fabric is thick or bulky.
How to sew a patch on by machine
- Pin or tape the patch so it will not move under the needle.
- Choose the stitch. A short zigzag follows a patch edge well, or use a straight stitch just inside the border. Go slowly and pivot at corners with the needle down.
- Mind the thickness. Dense embroidered patches and multiple fabric layers are hard on needles. Use a heavier needle, slow the machine, and hand-walk the wheel over the thickest spots. Machine sewing is best on flat, openable items you can lay under the presser foot.

| Job | Common choice | Notes |
|---|---|---|
| Thread for thick embroidered patches | heavy-duty polyester or nylon | A common starting point |
| Hand needle | sturdy sharp, embroidery, or leather needle | Match to patch and fabric thickness |
| Machine needle | a heavier size such as 90/14 | A common starting point; match to garment and patch |
| Best all-round hand stitch | whipstitch, backstitch to reinforce | Widely used |
| Machine stitch | short zigzag or edge straight stitch | A common starting point |
Sewing patches by surface
- Jackets and denim: flat and forgiving. Whipstitch by hand or machine-sew the edge. For a large back patch on a cut or vest, sewing is generally the preferred durable attachment method, since the patch has to survive wind and heavy wear. See our motorcycle back patch size guide and biker resources.
- Backpacks and bags: hand-sewing is usually easier because straps, panels, and linings are hard to fit under a machine. Sew through the outer layer only so you do not stitch a pocket shut, and avoid the thick seams.
- Hats and curved surfaces: curved and structured caps are tricky. Hand-sewing gives the most control on a curve. Sew through the front panel only, and take care around the stiff or foam-backed area.
- Thick or layered patches: slow down, use a heavier needle and strong thread, and a thimble or pliers to pull the needle through.
Sewing PVC and rubber patches
Molded PVC patches are attached by sewing or with velcro, not by ironing. Some PVC patches are manufactured with a recessed sewing channel around the border. If the patch has one, stitch through that channel, which guides the needle and protects the thread, and double-stitch for extra hold. Other PVC constructions may use a different attachment method, so check your patch. If you prefer a removable option, choose a velcro-backed PVC patch. At Panther Patch, PVC patches and UV printed PVC patches both come with sew-on or velcro backing for exactly this reason.
When to have it done professionally
Large back patches, structured hats, leather, and uniform work with tight standards are worth handing to a tailor or embroidery shop. If your order is large or consistency matters across many pieces, that is the safer route.

What is the best stitch for sewing on a patch?+
A whipstitch, a small stitch that wraps over the patch edge, is the classic choice because it holds the border down securely. Add a backstitch in high-stress spots for extra reinforcement.
What thread should I use to sew on a patch?+
Strong thread. Heavy-duty polyester or nylon is a common choice for thick embroidered patches. Match the color to the border to hide the stitches, or contrast it on purpose.
Can I sew a patch on with a regular sewing machine?+
Yes, on flat items you can lay under the presser foot. Use a heavier needle, a short zigzag or an edge straight stitch, and sew slowly over thick areas. A 90/14 needle is a common starting point, but match the needle to the garment and patch thickness.
How do you attach a PVC patch?+
By sewing, often along a recessed sewing channel if the patch has one, or with velcro backing if you want it removable. PVC is not applied with an iron.
Do you sew the patch on for me?+
We manufacture the patch with the backing you choose. Sew-on is our included standard, and attaching it is a quick job with the steps here, or any tailor can do it. A tailor, alterations shop or uniform supplier prices it per patch, so ask them for a quote. To skip sewing altogether, choose iron-on backing for fabric that takes heat, or velcro backing, which comes with both sides.
