Cutting mat. Self‑healing cutting mat provides a safe and precise working surface for cutting paper, fabric, foam sheets and other craft materials. The printed measurement grid makes straight, accurate cuts easier, while the 3 mm thick surface protects your tabletop from damage. The mat remains functional even after hundreds of cuts and also protects your knife blades from dulling on hard surfaces. A practical tool for sewing, model making, scrapbooking and general hobby work.
