16.75" Diameter Martelli cutting mat. Contains grid w/ lines every 1/4". Has a 10" square on the mat for squaring up fabric. Has Martelli no slip material on bottom of the mat.
The Round-About Cutting Mat was designed for use with the Round-About base. The mat is a different material than the commercial-grade mats, meaning that it is not self-healing and you can not iron on it. This is why there is the Round-About ironing top available for purchase. The mat has the Martelli get-a-grip material on the back side so you can use it with the base or in a stationary manner. It is also small enough to take with you on trips and use for classes.
