We use a combination of shelving / tubs in my son's room
IKEA and Costco have been our friends. OK-- his room happens to be clean so I ran up to take pix for this post.
From Costco I got the Seville Classics Cubes
in color. From IKEA I got little hooks and waste paper baskets (1.00 each). We hang the backpacks and dress up vests on the sides of the cube with the IKEA hooks. You can see there is a shelf we actually have inverted on top of the cubes; it is like that because these rental walls are CRAPPY and won't support it's weight. It will be hung normally when we move.http://www.wolfmeisters.com/July05/nickwall.jpghttp://www.wolfmeisters.com/July05/nickbucket.jpghttp://www.wolfmeisters.com/July05/nicktoy.jpg
We keep the bigger bulkier toys in the toy box, and use a long, shallow rubbermaid container (in the closet) for the wooden train tracks a la Thomas.
Downstairs in the school room (we do home-based Montessori), we have everything on low shelving.
Being Montessori-minded, it is very important to me to have a prepared environment for the children. The rest of the house is getting there in terms of organization, but we're not as "done" as the kids' rooms. They mess it up, to be sure, but they are learning that is is relatively simple to repair and clean up. I would like them to know from early childhood how to avoid becoming a grown-up Messy like me.
