I have these wire racks that are the biggest pain in the butt to put together, but they hold a lot of stuff. In the past I used them as soap drying racks, but ended up wasting a lot of space since I could just put 1 row of soap down and then there was like a vertical foot of air space wasted. Anyhow, this doesn't look particularly organized, but this is what I recently did in my crafting room that doubles/triples/quadruples as an exercise room/library/nephew play area (really, the tonka trucks and elmo tool bench--not mine) But I got the racks from costco I think. Anything you can get to lie on its side like that is great, milk carton crates would work well too! Don't forget to check the kids section when you go to the store too, sometimes they have cool kids organizational drawer type things. You can't see it here I don't think, but on the other side of the book shelf (that's all craft books lol) I have a 3 drawer rolling cart thingie with more yarn, mostly crochet thread and fun fur crud.
