I have the 12x17, the 18x24, and the 36x58 that covers my whole work table. I don't want to do without any of them!!! I use the small ones upstairs in front of the TV to cut apart HST and square them up. I use the biggest one even to cut fabric for draperies and other sewing projects!
Lucky me, but remember, I bought all of them when they were 50% off.
