Army in a box (a little box)
I've shown these guys off once or twice before, but I can't stress enough how awesome these little trays can be for sorting out parts. You can get them at the Dollar Store, usually the walls between compartments pop out so you can fit big bits like flag poles and spears and stuff with ease.
I finally finished clipping all my Wood Elf bitz and sorting them. Here you can see the ~30 Glade Guard, all the parts to make a few dozen Deamonette/Dryad models, 8 Glade Riders plus a ton of characters and leftover metal guys (Eternal Guard, Waywatchers, and the likes).
So yeah, if you can get your hands on something like this I highly recommend it, there's easily like 6+ regiments worth of models in a box maybe a third the size of a normal Regiment Box. Well worth $2.00 per tray.
