I too was searching for a way to organize my paper. I didn't want to spend a fortune, but wanted something practical and useful. I came across this idea (see site for an example of finished product being sold on e-bay below), but I made my own. Walmart, Target , etc. have the cube kits. Use some small plastic ties (found in the hardware section) to connect them. I got 2 kits for $6 each at Walmart and made 2 cubes with many shelves. I think they have been running from 7-13 dollars lately, but still a good bargain. I love them. You can custom build them to fit what you need and rebuild them if your needs change.
