I love that "rubbery" stuff. I have a length of it under my quilted tablecloth which is on a glass tabletop -- it prevents The Cat from using it as a slip n slide.... I also put it under the cutting mat on my cutting table. It's one of those big white ones, and the board that is the top of the table is that white-coated stuff that is slippery. This really keeps it in place. But hadn't thought to use it for the foot pedals. Cool!
