I got three of these recently and love them so much that I got another today. I'm going to give some to friends who DM.
I am thinking of cutting one into a 24"x20" piece, an 8"x10" piece and a 16"x10" piece. Since you can pre-draw a layout with Sharpie and it won't rub off while the mat is folded up, this would add utility.
My concern is the lamination. Will doing this cause it to peel? Is there something I can do to prevent such a thing from happening- a hot implement to seal up the edge, maybe? Or should I abandon this plan as insanity?
