Instructions for Ironing on a Patch

Tips for Ironing on Patches

Before you begin to iron anything onto your garment, please check what material it is made of. Patches can be ironed onto cotton, cotton blends, velour, denim and wool. For your safety, use a flat surface for ironing on a patch and follow any iron or patch instructions.

Tip: Cotton and polyester fibre blends work the best. Fleece blankets can be ironed on as long as you're careful and use a pressing parchment square or a thin cloth over the patch.

DO NOT apply iron-on patches to waterproof rainwear, rayon, nylon, velvet, acrylic, minky, leather, vinyl, or any other fabrics with finishes, elastics or heat sensitivity. If you're unsure, test with an iron on a hidden seam or hem to see if the fabric accepts the heat without damage.

Hand or machine sewing is recommended to permanently attach patches. The adhesive may not stick well on some fabrics or may peel off over time.

Iron-On Patch Instructions

  • An illustration of step 1.

    Preheat your iron to 350 degrees Fahrenheit (the cotton setting for about five minutes or until hot) and position your patch where you want it on the material.

  • An illustration of step 2; placing a cloth over the patch.

    Place a pressing parchment square or a thin cloth over the patch. EPC TIP: Use a damp cloth when ironing wool or other delicate fabrics. Also, make sure the cloth is damp, not soaking wet.

  • An illustration of step 3; ironing the patch through the cloth.

    Place your iron onto the cloth on top of the patch and apply firm pressure for about 30 seconds. Allow material and patch to cool for five minutes.

  • An illustration of step 4; ironing the back of the patch.

    Next, turn your garment inside out and iron the area behind the patch while applying firm pressure for 30 seconds. This ensures that the patch is firmly attached. Allow the area to cool for another five minutes, and the iron-on process is complete.

Sewing vs Ironing on a Patch

  • Patches can be sewn onto fabric or garments with a single or double stitch along the border of the patch for extra security.
  • Ironing on a patch can have a cleaner look, but ironing and sewing can improve the longevity of the patch (especially for clothing, such as sewing and ironing patches on denim jackets).

Care & Maintenance

  • When washing fabric with iron-on patches attached, make sure you turn the garment inside out.
  • Never wash in hot water or dry with heat or you risk loosening the attached patch.


  • If your patch is becoming loose, you can try to iron it on again. Follow the iron patch instruction above, but if that doesn’t work, you will have to sew it on.
