I am glad someone asked. I was thinking the other day about mats. I have one that I keep on the table section of my quilt frame. It is an old Dritz, almost clear with black markings. I could swear it was some kind of plastic and it was hard on the rotary cutter blades. I quilt using it and put it on the table to keep it flat and out of the way. I do not think it was self-healing. It says: "Super Cutting Mat" The number 1042 appears in the upper left corner of the label on the back. The store sticker has " N 193-9396" and the price was $14.50. I have no idea when I got it. Does anyone else have one of these and do you think it dulls the blades?
