Did you know that those dollar discount stores often sell foam liner for kitchen shelves that works every bit as well as the mats we buy for sanding or routing? For just a buck or so, I use these for those purposes, but I also cut them into smaller pieces to help unscrew stuck lids on jars or to get a better grip on screwdrivers. When they get dirty, just rinse and dry them. Or, when they tear, toss them out and buy another one. They’re so inexpensive, I won’t spend full price on a sanding mat again.
