I've just recently bought Sterlite containers and have sorted by colors. I haven't cut them into any sizes like Bonnie Hunter's idea on Quiltville and am still deciding if I want to do that, however, in the few weeks since I have done that much sorting I've cut down on my looking for a certain color time way down. I just grap the container with the color I want and see what I got. I try to use up the smallest pieces first, that way if I do decide to cut into sizes, I will have bigger pieces and be more efficient.
