I don't have a huge amount of lego. It all fits in a 60 litre tub. I have six chinese food containers (the plastic ones with a lid) in the big tub that have certain parts (tiles, 1x1 round bricks, signs, 1x1 plates, roof peaks etc.) in them, just so they're easier to find when I'm building.
The rest is loose in the tub. There's only the 5 main colours that we had for bricks and plates in the mid 1970s, plus trans clear bricks and the odd grey plate so it's nice and simple for me to pick the colours I want !! haha
