I have been sorting my legos by part. I bought a container that has drawers but I would need a lot of them for the amount of legos I have. I am limited in space. Any suggestions on what I should get? I want a drawer for each part and noticed that some of my 1 x 1 parts are in two to three drawers. Please help with any suggestions. I also want to be able to expand if I get more of the same parts.
