Don't overlook this great aspect of model hobbies! I have built a couple of doll houses now for my daughters. The hobby is fun, creative, electrical (if desired) and very rewarding. A really good place to start is Hobby Lobby stores. They carry a good selection of kits and accessories. Often, they have a 40% off coupon on their website too!
We are fortunate in central Indiana to have this really neat museum. Take your family sometime. They have other collections too. If you want to see the "ultimate" doll house, go to the Museum of Science and Industry in Chicago. There, you can see Colleen Moore's incredible."Fairy Castle" up close!
Yes, I know this isn't a local hobby shop, but its the "Biggest in the U.S.A." and they have the best inventory of doll house kits, miniatures & accessories of any place I've been to. Check them out. Visit them if you ever get the chance!
This is the brand I started with. Wonderful selection, great quality and well designed to go together really well.
The best local source of dollhouse supplies.
