How to Attach a Patch to a Hat

Whether you're customizing a Richardson 112, adding a unit patch to a tactical cap, or fixing a favorite trucker hat, there are three reliable ways to attach a patch: stitching, heat-pressing, or gluing. Here's how to pick the right method — and how we do it in our shop for maximum durability.

Which method should you use?

• Stitching — most durable. Best for leather, PVC, and woven patches you want to keep forever.
• Heat press — fastest and cleanest. Works great with iron-on backed patches.
• Fabric adhesive — quickest fix. Good for temporary looks or hats you can't heat-press.

Method 1: Hand or machine stitching

1. Position the patch on the hat's front panel and pin the corners.
2. Use a heavy-duty needle (size 90/14 for machines) and polyester thread that matches the patch border.
3. Sew slowly around the perimeter with a straight or zigzag stitch, keeping about 1/16" from the edge.
4. Backstitch at the start and end to lock the thread. Trim any loose ends.

For a curved front panel like the Richardson 112, unstitch the sweatband first so you can lay the panel flat, then re-stitch it after the patch is on.

Method 2: Heat pressing

1. Preheat the press to 320°F (160°C) for iron-on patches, or 275°F for leather.
2. Place the hat on a cap press platen. If you only have a flat press, use a rolled towel inside the crown for support.
3. Position the patch, cover with a Teflon sheet, and press for 15–20 seconds with firm pressure.
4. Let the hat cool completely before touching the patch — the adhesive cures as it cools.

For extra hold, we recommend following up with a few tack stitches at each corner.

Method 3: Fabric adhesive

1. Clean the hat panel with a lint-free cloth so the glue bonds cleanly.
2. Apply a thin, even bead of permanent fabric glue (E6000 or Aleene's Fabric Fusion) to the back of the patch.
3. Press the patch firmly onto the hat and weight it down for 24 hours while the glue cures.

Pro tips for leather patches

• Leather doesn't like high heat — keep press temps under 280°F and use a Teflon cover sheet.
• Pre-punch stitch holes with an awl to avoid tearing the leather.
• Waxed thread holds better on leather than standard polyester thread.

Skip the DIY — get patches pre-attached

If you'd rather have it done right the first time, our shop presses and stitches leather, engraved, embroidered, and printed patches onto Richardson, Flexfit, Comfort Colors, and District caps. Every hat is quality-checked before it ships.
