My DH takes my old ones and uses them in his shop. He put one on a top of a cabinet or something and he can use it when he needs to cut something with one of those retactable razor cutters that all guys have...LOL( I have a couple as well). He used one for a neighbor that wanted him to make a fish cleaning station for him...he screwed the edges down on a treated piece of plywood next to the sink for the cleaning station...works like a champ! Now they can clean the fish and not cut into the wood and it can all be cleaned and hosed off and be outside in the weather. I have also cut one into smaller pieces, using the sections that I didn't "use up" to have little cutting areas next to my machines and to carry with me when I need a small cutting mat.
