I never wanted to start this tradition. It looked time consuming, tough for little fingers, one of those activities that the kids end up watching the parents do.
And then I bought one of those kits, just because it was on sale...5 years ago. Every year since, we have built a house (or houses, this year) and every year I'm pleasantly surprised how much fun the kids have making them. I do have to help with the construction, but the decoratin is all them.
