I'd like to hear how those out there with large collections store and sort their lego. And how it affects your build methods.
I'll start. For large collectors I have a medium size collection (about 500 lbs).
I store all my Lego in sterlite craft carts. Specifically the ones with the drawers with lids, that slide out of the cart as a stand alone sealed plastic boxes.
I first have them all separated by color, each color gets its own cart. i then segregate each color along the lines of the brickset categories with a few small differences.
For minifigs I use the acrylic cases from the container store. Both the 2x7 and the 3x9 cases and display them on the wall.
This allows me to find whatever part i need fairly quickly, but does mean that to build anything i need access to allot of drawers of lego. How do you guys sort and store?
