You say you want a compost bin?
Groves-Raines Architects have designed a compost bin out of rolls of reinforcing rods. I love the delicate weave pattern formed by what has to be a pretty heavy "yarn".Hope you enjoy it as much as I do. http://www.grovesrainesarchitects.com/projects/project/106.

This is awesome. Can I have one for my future backyard? Thanks for sharing!
