We shared our first annual "gingerbread house" making party with Grayson, Vance, Gavin, Avery, and Micah the day after school let out for Christmas break. We used graham crackers for the walls and ceilings and then just icing from a tube to glue it all together. The tube icing is a great idea for cutting down the mess (as opposed to Royal Icing), but doesn't dry hard enough. When the boys went to decorate the houses, they all collapsed! It was fun, though, maybe next year we'll try the R.I. instead.
