Iron on instructions: Not all our patches are iron on, see the discription in the auction to see if that patch is iron on or sew on. Most iron on patches can also be sewn on. Place the patch on the garment you want to attach it too. We do not recommend ironing patches on silk, leather or other delicate garments. Place the iron on the cotton setting. Please a thin cloth over the patch, this will protect the patch from transferring any dirt of the iron to the patch. Iron the patch in a circular motion for about 30 seconds. Turn the garment inside out and repeat the ironing in circular motions (keep the iron moving). Let the garment cool for 10 minutes before wearing. Washing the garment. Turn the garment inside out when washing.
