I have all the brands in one size or another. I like June Taylor the best, the rotary cutter doesn't cut into the mat, it rolls on top of it. But the JT mat has awkward sizes. The bigger Fiskars or Olfa mats fits better on top of a table. Do not put it in a car seat or stand it up in the floorboard to bring it home from the store. It has to be flat at all times. Lay the mat on a flat surface before you buy it. One little wave and it's there forever. JT mats do not warp so I leave one in the trunk of my car for classes/workshops. It's been four years in the trunk and still flat as new.
