From Lori Holt of Bee in my Bonnet.
This is a must-have cutting mat to keep close to your sewing machine. The size is absolutely perfect!
Double-sided, triple-layered, 3mm PVC for superior self-healing and longer life. One side is blue and the other side is pink. And yes, there are grid markings on both sides. (Woohoo!!!)
Extra room along the edges for more stable cutting. The grid markings are 5" x 8", but the total outer dimensions of the mat is 6" x 9".
