The most innovative book arrangement: Cool DIY pipe book shelf.for the industrial looking living room.all parts can be bought at home depot, and they will even thread the pipe for you there to the length that you need it! Maybe for bedroom idea.
DIY: PVC Pipe Shoe Storage - so fun and so simple, could easily spray paint or cover in fabric or paper too. maybe a horizontal layout of two rows or something. I think this would be good for garage "yard shoes" storage
