I have super size mats in both AZ and CT, because I have big cutting tables. When I'm working on a quilt, I gradually use up all the table space, so it's great to have the whole top as a cutting mat, so I don't have to constantly move things around. Wait for a sale, and buy the Omni Grid mat - or get Sure Fit on-line. I have O in AZ and SF in CT - like 'em both.
