If you love Horsetooth AND Colorado, get this patch and throw it on just about anything. It’s got an iron on adhesive on the back. However, depending on the application we highly recommend also sewing the patch on. We cannot guarantee the application (how you apply) so we cannot guarantee the iron on adhesive’s ability and lifespan. If applied correctly (& on the correct fabric) the ironed on patch should stay adhered for 60 washes. Colorado Iron on Patch Instructions Heat iron to the Cotton setting (makes sure it’s completely heated up). In a circular motion, iron the fabric/garment that the patch will be attached to. Make sure that the fabric content you are using is capable of being ironed at such a high heat. Synthetic and delicate fabrics (like nylon, vinyl, leather, silk, etc) should not be used. Once the fabric/garment is sufficiently hot, place the patch exactly as you want it, cover with a light cloth (a clean dishcloth is good), and iron in a circular motion for 30 seconds. Turn the fabric/garment over (carefully, don’t pull at the patch) and iron in a circular motion for another 30 seconds. Let cool completely (a few minutes). Test the corners to be sure they don’t pull up. If they do, repeat steps 3 & 4.
