Are there any US dollhouse manufacturers that don't use an open back design? Open back equals dust collector. I like the way the British houses are made with a door. I am working on the Greenleaf Orchid and have decided how I will close the back but any suggestions on how to close the roof? So far the only thing I have thought of is a piece of plexi or polycarbonate hinged to the roof but then would it open and stay open when in use. haven't quite figured out the mechanics of the shingles being in the way.
