Step 6: Classification and Storage
You can do what you want, it's your stuff, but it helps to classify it and store it so you can find something if you need it. For want of a better system, I recommend sorting your collection into the following groups: Metal stuff, plastic stuff, paper and wood stuff, tools, actual hardware, and everything else. You can further divide it into sub-categories but it's probably best if you don't. While searching for one thing, you may well encounter something else that works even better.
A friend of mine once invented the universal solvent; it would dissolve anything, He just couldn't find anything to keep it in. (<= JOKE)
Same thing here, you have all these neat things, you can't just throw it in a pile. You have to have something to keep it in. How about:
peanut butter jars, oatmeal boxes, plastic jugs, Gatorade bottles, Altoid tins, egg cartons, ice cube trays, cookie tins, pill bottles, plastic cups, detergent bottles, and a lot more.
