No no no, that's not a POOP. A poop is a Piece with Only One Purpose, like, say, a minifig rifle, backpack, or other thing. That big mask is just a big POOP.
Also BURPS are Big Ugly Rock Pieces, Ya know, those things. Yeah, those.
I have a half my Legos organized into bins by color. That's very useful when building anything with a color scheme, obviously. I also have a few drawers of tiny pieces, you know, small things used for SNOT and greeblies, anything smaller than a 2x1 (called "two'ers" by me & meh bro). Then I've got my minifig box, organized also. 3 drawers, one for pants, one for torsos, and one for heads/headgear. I also have my yummybox. It's like a big red open-top tacklebox that I put all these useful pieces I find when digging through my unsorted boxes. It has sections, like 'useful pieces', 'little pieces', 'controls/panels', and a bunch of tidbits that you find when you are looking through. Every builder knows how this happens; you find some things that you think you might use later/are cool, and you put them, in Blitzen's case, on top of boxes or elsewhere in your area. I used to do this, I put them on top of my bedside table and eventually I had a huge overflowing pile of stuff that was a pain to go through. That's why I have a yummybox.
So ANYWAY, COLOR is the way to go. NOW.
