In my parents' basement is a 3 foot tall doll house with working lights and tons of expensive furniture.
Although, I think I would have liked this better: The Perfect Dollhouse
I love that not only is it made entirely of recycled goods, but, if made the right size, it can slide right under a bed.
Look through the whole article. They have some great ideas for furniture and accessories.
I can see we're going to be busy around here. We have a home to build, decorate and furnish.
