A box for each kid K-12 ... I had a professional organizer at my house (what a treat!) and she suggested this system for pictures and papers, etc. 1st year, 1-2, 2-3, 3-4, pre-K, K, 1st grade - 12th. So simple, but so brillant.
Bedroom organization...I think I might use this idea, combined with the shoe-box-covered-in-scrapbook-paper idea for the bedroom....if we need it....so i could stack them or put on a shelf like this and it would still look decorative
