I mentioned to Husband, a civil engineer, today that I think he should build me some houses so I can make these. To my surprise, he got right on it so I will soon have an adorable, nearly free collection (or set depending on how long it holds my interest). I've been in a Christmas decorating slump but no more. Yeah!
If you love them and want to save yourself the trouble of making your own, my new favorite online site, Jayson Home and Garden, offers them prefabricated with free shipping and they're perfect.
