This was such an economical way to add a very upscale look to my kitchen!  I have white marble countertops with a walnut island and white cabinets with unlaquered brass knobs.  Everyone who comes into my kitchen compliments the backsplash.  It looks great.  I used a white sanded grout because the grout lines are a little large and it adds a great texture with the matte grout and the glossy tiles.
