The Creative Grids® rotary cutting mats are self-healing and double-sided. These mats are a great choice as table mats inside your quilt shop or studio. Our 5 layer cutting mat gives you two cutting surfaces and two separate layers of self-healing material. The second side is printed just like the first, doubling your cutting area. Both sides feature 1in grid with 1/8in markings. Work from either side of this studio sized mat. One set of numbers run across the 58in side and up the 28in side on the left just like our smaller rotary cutting mats. If you want to work from the other side of the table, the numbers on that side will be right side up doubling your cutting options. Numbers are printed inside of the grid area, giving you more grid to work with. 1/8, 1/4, 1/3, 3/8, and 1/2 yard cuts all the way up to 1-1/2 yards are marked for easy reference from both sides. 45 and 60 degree diagonal lines are included and start at zero in opposite corners.
