The Creative Grids® Self Healing 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.
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!
