These pin boards are for use with the plastic tube beads. Create your design on the board, heat the beads with an iron (using an ironing sheet/baking paper over your design) and the beads will fuse together! This pack of 5 contains one each of 8cm square, 8cm diameter circle, 8cm hexagon, 8 x 6cm heart and an 8 x 9cm star. We also have a pack of 3 larger pin boards available.
