I bought a small piece of the shower pan liner too and taped it down in my studio. All of my footprints show up and it tended to turn with me. I think it would tear pretty under my kids violent tap shoes. I had a sample of Alva's Matlay reversible black & gray with me. The shower pan liner was less than 1/2 as thick as the Matlay. Perhaps we should all pool our resources and buy our own Marley company to give out Marley-at-cost to all of our friends forever! The shower pan liner was, however, an excellent idea to try! Thanks!
