Sometimes a picture needs almost no explanation:
The clothespin-hanger
This great idea solves the problem of how to dry all the clothes in the laundry at once, and also helps rid laundry of clothespin marks. I would imagine that these clotespin-hangers would also double as regular hangers once the clothes are dry.
The sheer simplicity of these hangers is what impresses me most about these innovative and creative hangers.
