Sounds like a neat idea. It also made me wonder about those 5 or 6 extra mouse pads that I have been trying to get up enough nerve to toss out. I wonder if I could cut out a double flip flop, cut holes in the top one, rubber glue a strip into the holes between layers. That might make flip flops strong enough to wear out in hot beach sands or back yard gardening, complete with messy water hoses.
