The Sizzix Cutting Mat is a must-have accessory for any maker. The double-sided, self-healing mat provides a smooth, gouge-free surface so you can be confident that every cut is precise. Precision measurement grids are printed on both sides of the mat, providing both imperial and metric measurements, as well as a 0-to-90-degree angle guide that takes all the difficulty out of accurate cutting of paper, fabric, felt, chipboard, mat board and other materials. At 12 7/8" x 17 1/8", the Cutting Mat is big enough to manage larger, scrapbook-sized papers and materials, but still fits neatly on your work surface. At just 1/8" thick, it's easy to store or transport for making on the go.
