I'm actually looking into doing this with my boys. I work around the block from a cigar shop and found they sell the cardboard cigar boxes for $.24 each. So I'm in the process of building one to see how I can have the boys do it in one sitting. You could also build a cookie tin banjo. Seeing how the holidays are around the corner those butter cookies are going to be plentiful.
