I finally found an on-line source for some art deco accessories. Check it out:
This site is amazing. A number of the galleries have stained or leaded glass products for an art deco dollhouse, including doors, ceiling panels, folding screens, and fireplace screens. They are too, too wonderful! My latest idea is to try to get to the Philadelphia Miniaturia (http://www.philadelphiaminiaturia.com/) in Cherry Hill, NJ this November and see some of these things in person! Would love to buy them, but probably won't be able to afford much.
