I have the Martelli cutting mat. I've had it for over 5 years. They are 2 sided. One side is yellow and the other side is purple. It also has a grid for squaring up blocks. It has been rolled up and left in the car when it was hot. It went back to lying flat. They are pricey but well worth the $$. When you buy at a quilt show they are cheaper. No fuzz. I make a lot of quilts a year and no "cuts" on the mat.
