We need help getting our 6 year old's collection under control, ideally using the setup we already have. I'm thinking we ditch the deeper bins and just get more of the shallow ones then put dividers (or inserts)in them so we can sort by part type then size? Is there some off market clear bin that we can use instead? Our son is advanced with Legos, but needs help with an organization system that he can manage himself. He prefers sets rather than free building, so we started by separating pieces into sets but that collection quickly grew out of control.
