Organization Potential

Right now, my Bible class stuff is organized ... sort of. I have a two-drawer filing cabinet packed to the brim with various folders for stories I've taught or ideas I've collected through the years. I also have a large plastic tub full of more ideas and craft examples. And another smaller tub of more craft supplies. And a poster box of various visual aides. And another box or two of more things I brought home from my mother-in-law a few years ago. See my problem? I have to dig through more than one place to find what I'm looking for most of the time.
So, when I found this beauty on the marketplace a month or so ago, I pounced on it. (Please ignore the mess surrounding it. The garage is on the to-do list for this summer.)

Five empty drawers, just waiting for me to sort various crafts and ideas and papers into them so that I can have a better chance of finding something. I'm completely thrilled with the potential.
So, I'm curious. How do you organize your Bible class materials? Do you have a system, or are you more of a "dump everything into a bin and find it later ... or not" kind of person? I'm always looking for great suggestions!
