I tried to find a custom sized mat, self-healing to fit my cutting table. Finally ended up making the table to fit the mat. Self-healing on both sides, one side is green with markings and the other side is black with marking. I added a piece of wood trim around the table up just enough to be even with the mat.............to keep the mat from shifting......not that it would as its not light weight. I also glued the corners down as the mat came rolled up. Love my mat but found that the markings are not true to measurements.
