Mombo....the last time that I bought those 12 x 12 squares they supplied some tabs that had adhesive on both sides. Maybe now, you have to buy those seperately...but...they really do a pretty good job of keeping the tiles in place. The tabs are relatively small....something like an inch square (give or take). They are kind of spongy, but not thick, so as to work with varied surfaces. Mine were applied to a wall and I never had any of them fall.

John....let us know what you find out about that table.....that really sounds nice. I'm interested in hearing more about that, too!
