I liked the idea of doing the birch tree wallpaper in a half-bath. But it never occured to me to have branch (not necessarily this one) wallpaper on the ceiling. (Oh, and obviously, I'd have 'lantern sconces' on the wall, instead of a ceiling light.
Minimalist bathroom design with textured walls from FCP Ceramics - great matching of colour & texture. The bathroom uses a range of texture walls. These make a natural colour room have texture within them and therefore are more interesting.
