My wife has an artistic food streak. So until the kids could add their own distinct touches, she made gingerbread houses. I mean all natural real ingredients, edible and no cheating. Some years the houses would lean a bit. It’s hard to get that powdered sugar to glue things well. Later she stopped. The kids haven’t done it much recently so it’s a tradition lost until there are little kids running around once more. One year she baked/assembled one and gave it away as a gift. The hostess wrapped it up and stored it for the following year. We just eat ours. The kids like disassembly as much as construction.
