This 12" x 18" mat is a double-sided work surface for stamping, die cutting and more. One side has a soft foam and slightly flocked surface - perfect for piercing, using the brush side of the Tool 'n One, and stamping. The other side is a self-healing surface - perfect for cutting and general crafting. Also on this side of the mat is a one-inch magnetic strip along the top edge to hold items such as our die templates. Both sides have measurement grids.
