My kids love to decorate gingerbread houses. I buy the pre-packaged kit every year and it's a fun tradition. You can see previous creations here (2008) and here (2007).
The worst part of the process is assembling the walls and roof. You have to mix the icing and pipe all the sections carefully. I usually prop up the walls with cans of soup and jars of peanut butter while they set. The kids always want to "help" and that does not make the process any speedier.
Until this year...
I thought we could try putting the pieces together with hot glue. I mean, we don't eat the house, so why worry about edible elements?
Why why why did I not think of this earlier? It worked great. In fact, it was so fast, we couldn't even get a clear picture of the process!
