For me at least, winter means gorging on way too much candy. It also means staying indoors more often. I can only assume that the first person to make a graham cracker house (or gingerbread house) felt the same way.
I promise it's not laziness, but I love to do crafts where I simply provide materials and let the kids get as creative as possible. That's what I did today for our graham cracker houses, and I was not disappointed. Once they got the walls to stay up, they got busy decorating or, in one case, building a graham cracker outhouse.
