I stamped the words to a piece of cardstock cut to fit the lid and added some buttons.
This is what I put inside. Target had these cookie cutter sets and sprinkles sets for $2.50 each. I thought they were a steal and not overly cheap looking for a cheap price. The sprinkle set came with 5 different containers in it by the way, but I used 3 for other projects. I added a note that said, "Here is a kit to help you make Santa some cookies for Christmas Eve. I hear he likes extra frosting and sprinkles."
