My DW saw some "Instant Mosaic" tape on wall tiles at Home Depot. I'm thinking to doing this same mod but with these tiles. Just don't know if the 1/8" wall would flex and cause the tiles to pop off. Hate to have to redo the wall some other way if these tiles failed. Here's a link to one example of the tiles.
Instant Mosaic tape on tilesProbably the best thing to do would be to go to the store and look at the display. they have a good brochure that lists the colors and installation instructions.
