The Crafter Foam sheets are adhesive backed. They may be used for die cut plates by simply die cutting them out of a piece of the foam, peeling the adhesive liner away and applying them to the face of a die cut graphic. This allows the crafter to remove the paper easily. Crafter's Foam can also be die cut to add dimension to a flat die cut. <br> <br> 8 sheets per kit. 4.5" x 5.75". Adhesive with liner on one side.
