towel rods on the back of the door- great idea for a space saver. Just need to make sure there's a door stop so they don't hit the wall :) was thinking of wallpaper on the back of the door behind the towel rack
Or use a staggered bookcase system for a more airy feel.
This space turned a room divider into art with a gallery wall. By filling the entire wall, the floating wall becomes both the backdrop and the focal point for the living room. Photo by The Apartment via Style Me Pretty Garden Decor
