Originally I had my finished things just dropped in a box with the room name on the front - Bathroom, Kitchen etc. This proved to be a rubbish idea; stuff got jumbled and could be easily damaged and very soon I discovered that a particular chest of drawers or chair or whatever could go in several rooms and I didn't have fixed ideas for what I wanted where.
Here's my solution:
These boxes came from Wal-Mart last year for $2.50 each from the bead section and are a perfect fit for this teeny stuff. Hope I can get some more this year.
