Gingerbread Houses

Each year for Christmas we make gingerbread houses. The children have so much fun and do a great job! I prepare each child a house made out of graham crackers and give each child a can of icing and a bag of candy. The children are given around 20-25 minutes to decorate their house into a masterpiece. As you can see from the pictures they did a great job and had a fun time doing this project. All the icing and candy do not make it on the house. I wonder where it goes???
