When I purchased my last cutting mat, I got the biggest one I could afford at that time. DH took it to his radial arm saw and cut it in 3 sections about 18" each. Now I have one I have never used and two that are used in 2 different cutting areas--one on the back of my Hinty Stretch Frame for trimming quilted quilts and one at my cutting table.
