Give yourself room to cut strips, blocks, and borders with this OMNIGRID self-healing cutting mat for quilting and sewing projects. The mat measures 18 in x 24 in (45.7 cm x 61 cm) and provides a gridded side for measuring and angle work, plus an unmarked reverse for quick cuts. Store flat away from heat and direct sun, and rotate where you cut to help extend the working surface and reduce premature wear.
