The Creative Grids® Rotary Cutting Mat is double-sided.
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 designed to use with the Creative Grids® Stripology series of rulers. Line up the fabric and rulers on the spaced horizontal half inch grid lines. That is all you need - no other distracting markings and lines are needed!
