I am trying to figure out colors and decoration for master bedroom. The bed will be situated in front of the short wall which is like a headboard. The two doors behind lead to bathroom (left) and wardrobe (right). Am thinking of dressing the short wall with a wallpaper and also the back wall of the wardrobe (which has white doors). The actual headboard of the bed is a grey/white/beige fabric (see photo). Floors are dark walnut. I want a warm, relaxed setup. Any ideas on wallpaper and colors?
