This is a 5" x 9" non-stick work surface that you can put your fabric on to protect your counter top, table, ironing board, etc., when you are heat setting the HotFix rhinestones, rhinestuds and nailheads .
When heat fixing any HotFix Crystals, rhinestuds, or nailheads to fabrics and clothing, especially any fabric with an open weave like gauze, there is a chance the glue will seep through the fabric and adhere to the work surface. So, place one of these non-stick craft sheets beneath the section of fabric you are working on, and the problem is solved. Rather than sticking to your work surface, the glue will not stick to this sheet and you can continue working without delay. Also use this inside, between the front and back of your clothing item, so the front won't stick to the back when you melt the glue. You can use these over and over.
