I ordered my mat from Rhino. If you Google extra large cutting mat their web site comes right up. You can custom order any size, with or without the grid lines, to fit the space you want. It is a self healing mat and I like it just as well as the Olfa, etc. It's probably 5 to 6 years old and still like new. I have a piece of 3/4" plywood, 4'x8' that fits on top of a pool table. My mat is 35"x71", green in color and with grid lines and I love it. You might check it out Janice and see if it would work for you.
