Final product came out great! I was hoping to install it in bigger sheets, but once I started with the weird shape of my kitchen walls, I found the easiest way to get the stickers to stick without bubbles or folding over onto itself was cutting the tile pieces out one by one.  Yes, it will take you longer to place, but its easier to fix one tile than to peel off 3 or 4 at a time. Make sure you buy a good long ruler to cut the pieces straight, a wallpaper scraper for getting any bubbles out, a box cutter if you need to cut any extra thin slices off while it already on the wall.
