I know the North Dakota Duncan's will relate to the dilemma of what to do with humungous amounts of Legos and while visiting in California this week I was really impressed with Aunt Angela's idea to organize the chaos!
These are regular Legos organized by colors. They are containers from Ikea that fit under a bed. Then Aunt Angela put shoe box size containers inside of them to house the various colors. My camera ran out of batteries but she also had shoe box containers with lids on them and various sets were put in those to go into the closet. The direction book and Legos for those projects are kept in there.
These three boxes contain all of their Bionicle pieces.
Impressive Aunt Angela!
