I used this on the bathroom wall above the wainscoting.  I saw, maybe on the Wayfair site, .that someone had cut up the pieces and made an irregular pattern around her kitchen backsplash.  It looked interesting so I modified it and cut the sheets apart into strips (scissors) then stuck them on above the wainscoting molding in a strip of two levels of tiles (an inch each) then put individual tiles in different designs above the strips of tile.  Looks really neat and not hard to do at all.
