Place heat transfer decal in location you would like. Place a clean white towel over decal and carpet. Be sure to not move decal from location you would like it when placing towel on it. Get iron to roughly 350 degrees and apply pressure to area of towel that decal is. Take it easy and check to make sure decal is adhering. It is a far superior process than a peel and stick type decal for carpet. If you would like to remove it or any other heat transfer acetone on a paper towel will do the trick.
