These worked great and are very pretty once I figured out how to use them. It's pretty obvious but I still was hesitant to maybe ruin my clothing or waste one on a test, instructions would have been nice. Peel clear plastic off backing and apply to clothing. Turn over and iron inside of clothing. I found it helpful to press down on the iron. I checked every 10 seconds or so for glue through the fabric and to make sure nothing burned. Lost one rhinestone from my first try as I did not heat long enough for glue to melt into fabric. Very happy with results.
