I have the June Tailor mat. I had difficulty with my larger rotary cutters but my smaller cutter went through with no difficulty. I recently used mine for cutting binding, sashing and strips for pieced blocks. If you put your hand on the right spot, the mat does not slip. You can also put the little pads underneath to keep it from slipping. Once you get the hand of it you will not go back to a regular ruler for cutting strips.
