Coaster for Perler Sprites

This coaster has been designed to hold 16x16 sprites made of Perler beads. It will, however, accommodate up to 17x17 beads. The bottom is solid and the lip around the outside is taller than the beads to allow for surface protection and easier stacking/storage of the coasters. I glue the sprites to the coaster using clear Gorilla Glue however they could also sit in the base to allow for changing the coaster design.
