Creative Grids Self-Healing Double Sided Rotary Cutting Mat 12in x 18in

One side features 1" grids with 1/8" marking over the entire surface.  Popular 1-1/2" cuts are highlighted with white stars; 2-1/2" cuts with white squares.  Eighth, quarter and third yard fabric cuts are marked for easy reference.
The opposite side is designed to use with the Creative Grids Stripology series of rulers.  Line up the fabric, strips or blocks on the spaced horizontal 1/2" grid lines and let the marking on the rulers do the work.  No other marking and lines are necessary
