I put the smaller ones in a pants hanger with a piece of that sticky shelf liner in between the hanger and the mats (so they don't slide out of the hanger). This is the kind of hanger that would clamp over the cuff end of a pair of pants. Then they hang in the closet. Actually, most of the time they are on my sewing table, but I can leave them out all the time. I've no pets or kids with sticky fingers around.
