What do you do with your crutches after that nasty crash on bicycle? Well, if the wheels are still in good shape you could always make your own stool to commemorate the occasion. Then again, you can find old crutches and some wheels in the recycling and/or garbage and forgo the whole bicycle accident part.

Very creative, I like it. Everytime that I go into a thrift store I seem to find lots of crutches, so I imagine that would be a good place to score some materials for this project.
