Dylusions Dyamond Boards - Hexagons are a perfect foundation for crafts and art projects such as journal covers. Pre-primed and die-cut, they make it easy to use Dyamond Rocks, Dyamond Medium Dabber, and Dyamond Dust. Cover the board completely with the Dabber and add a layer of Rocks, tapping off the excess before heating to melt. Repeat with two more layers for a smooth finish. For debossing, ink a stamp with Dyamond Medium and press into the third layer while hot, then dust with Rocks. 20 boards in each pack measure 7.3875 x 4 x .45.
