I haven't heard of such a thing, Louise. All I can think of would be to mount the tile on some sort of board, rather than to your wall.
Louise, is this what you're looking for? http://www.hometalk.com/438229/kitchen-backsplash-it-s-not-tile-it-s-a-decal
If not, maybe it's on this board: http://www.hometalk.com/b/149284/backsplash-ideas
I found it.....thank you so much for the help!!!!!!!!
Louise please post them as I have never heard of them either!
Check out Dali Decals....Mosaic tiles!!!!
Thank you Louise.
