Katie brings home many pieces of artwork from school. Yesterday she brought home a gingerbread house. The "house" itself was a box covered in brown construction paper. I thought that was an easy way to make the structure without having to bake a lot of gingerbread. They used icing and candy to decorate the rest of the house. That made it much less involved, which I think is key when dealing with 3 and 4 year olds.
