Building Cookie Castles! I purchased small, square, sugar wafer cookies at an import store (Cost Plus). Each child had a foil-covered piece of cardboard with their name on it (prepared in advance of the guests arriving) waiting at their place at the table. They were each given a bowl of cookies with assorted candies mixed in and a bowl of white frosting. They created castles by dipping their cookies in the frosting and building with them like blocks. The frosting served as their "glue". They were very creative and they loved this activity!! We had plenty of wipes on hand to clean messy fingers and faces!
