This mini double-sided Creative Grids Self-Healing Rotary Cutting Mat is 6 in. x 8 in. and designed by Gudrun Erla of GE Design. One side features one-inch grids with eighth-inch markings over the entire surface. All numbers are printed outside of the grid area, so they are always visible. Popular 1-1/2 inch cuts are highlighted with white stars; 2-1/2 inch cuts with white squares. Eighth, quarter, and third yard cuts are marked with dashed lines for easy reference. The other side is blank -- perfect for trimming blocks and paper-piecing.
