Martelli's 12″x 18″ cutting mat is made from commercial-grade materials, so it is very durable. With the proper use of their ergonomic rotary cutter, the mat is self-healing. It is also double-sided for the contrasting of colors. One side is yellow (for darker materials) and one side is purple (for lighter materials).

The measurements are printed along the outside of the mat and along its center axes so you don’t have to worry about covering up your numbers with your fabric or rulers. The mat also features 45-degree and 60-degree angles as well as concentric squares for squaring up your blocks. To increase the life span of your mat, we recommend you use Martelli cutters and blades.
