I just purchased a titanic roll of the foamy matting. It's about $4 for a large, large roll of the stuff at Menards. Used for lining shelves, it seems like something I can use that will be disposable, so my blues or whites can sit on them in the cave for weeks, and when done: tossed.
Anyone else tried the foamy matting?
I figured I would cut a nice bit and dunk in StarSan for a while before using. Just in case.
