Add some sparkle to your home by embracing metallic accents. Walls, kitchen backsplashes and accessories are all blank canvases awaiting a little touch of shimmer. Even the smallest touch of sheen could be just the thing to update your style. We love all of the metallic wallpapers by British designer Villa Romo, especially this cheeky raspberry and silver number. It would make a great accent wall, if you're daring enough to try it.
