Uxcell 12Pcs Iron on Patches for Clothing Repair 3"x4-1/4" Fabric Patch Cotton Decorating for Clothes Pants Green

I was looking for a dark grey color that matched a baseball cap I have and this was perfect. I practiced on a different baseball cap with a heart I cut out. I outlined the design from a template onto the patch then cut it out. It was easy to do that. It worked perfectly. I set my iron at polyester, moved it around over the patch while holding it down for 20 seconds. Unfortunately instructions are not included but Google helped :)
