Back when we were putting our nursery together last year, I found this great tutorial for the cutest, cheapest bookshelves ever. They're made of - wait for it - plastic rain gutters. I think our whole set up (pictured) cost less than $20 at Lowe's. You can probably figure out how to put them together just by looking, but in case you want the step-by-step, check out the detailed instructions at Raising Olives.
