This year I found the best thing, I got a gingerbread house already glued together, we just had to decorate it. It was perfect, because every other years ours collapses and we end up throwing it away.
I let the kids do it all this year, every single bit of it. I just sat back and watched. Its fun to see kids use their imagination and I struggle sometimes with letting my kids do things on their own like this. But not this year, I think it shows so much more than when I do it and try to make it look like the box has it.
