I take every bit I can get my hands in, then sort them into slotted compartments and meth baggies like some sort of mental defective.
I am a HUGE bits slut. When I went to my first battle bunker, there was a number of people working on minis, and I stepped on a plasma pistol bit. I asked whose it was, and the guy said, "oh, it's just garbage." I looked around, and the floor had all kinds of discarded weapons bits, decorative bits, and what have you just lying there. So I spent the next thirty minutes combing their floor like a homeless man canvassing for spare change in a parking lot.
