Around here I have more odds and ends than I know what to do with. I used to keep it in piles strewn about our tiny apartment until my fed up girlfriend came up with a solution to make the room a little more organized.
It basically involved drinking a lot of bottled water and using the jugs the water came in to store stuff. Using her method, not only do you get a $2 rugged modular plastic storage bin, but you also get 2 gallons worth of drinkable water for free. I highly advocate such a storage system. Especially if you are overrun by small parts.
Step 1: Drink water
Before you can even consider starting to store stuff in the plastic water jugs, you have to drink the water they're holding. It's recommended that you drink 8 full glasses of water a day. However, drinking a little more than that will not hurt you and may, in fact, be beneficial. If there are two people drinking water from the container, you should be able to go through one in about two to three days.
