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
Linen Closet Organization - Maximizing Small Spaces
Linen Closet Organization - Great diy post showing how to organize a small space for a family. I like this because wash cloths and hand towels take up weird space in the closet and get bumped over too much.
Over the door storage for a small Bath with limited space and no linen closet. To maximize space in the bath add a shelf over the door to store extras like toilet paper and extra towels. What a difference such a small change can make!
