OLFA® Cutting MatsLightweight OLFA Cutting Mats make the ideal surface for working with fabric reinforcement. Lay them out on a solid tabletop for measuring fabric and making clean, consistent cuts every time. They are designed to withstand punctures and slices associated with rotary cutters, razor blades, and scissors. Soft, flexible rubber eliminates the risk of damaging snags to reinforcement. Each mat features a one inch grid, marked with 18" increments. Mats
