We saved money using a standard 3x6 white subway tile from Home Depot. Even though our backsplash tile choice was cheap, it's still a classic look and I really love the way it looks all the way up to to the ceiling behind the open shelves, and around the kitchen window. I also really love the light grey grout we selected. It is subtle, but really makes the tile a feature in the kitchen.
Lay a thin strip of “backsplash” tile in between the large tiles, instead of just using grout. But my spin on this idea is... Black and white checker board tile and dark green or red back splash. Would make it look like Alice in wonderland theme
