Dylusions Dyamond Boards are the perfect substrate for use with Dyamond Rocks and Dyamond Medium. Finished pieces make great additions to journal covers, mixed media, art journaling projects and more! Dyamond Boards are die cut and pre-primed for easy use. To use: Cover a Dyamond Board completely with the Dyamond Medium Pad and add a layer of Dyamond Rocks. Lightly tap off excess. Heat to melt. Then quickly add a second layer while it's still hot and melt. Repeat with a third layer, until smooth. To deboss an image, ink a stamp with the Dyamond Medium pad and press into the still hot third layer. Each shape available in a pack of 20 pieces.
