Shelves.

[muskry.livejournal.com]

Does anybody have an idea for how to make some kind of shelving system for either folded fabric or books? At the moment, I have cardboard boxes draped with fabric as shelves, but they're starting to sag and the books are falling down. I don't have the extra cash to even go to Ikea right now, so it's time to get creative. Help?
