We order food from a Chinese restaurant on an almost weekly basis. With every order we receive some chopsticks, which we won't use. For some reason I collected them for a while and thought about what I could do with them.
A few weeks ago I had the idea to build a bookshelf with the chopsticks.
The idea I had was to place every book on two sticks, then pile the sticks on top of each other in an rectangular way and then hang the shelf into a corner of my room. I'm very happy with the results even tough it is not quite finished yet. (More sticks necessary...)

I will need more sticks to finish. Right now the shelf looks like this with books:
