My sister, Janet, sent me these pictures of her 3D Cookies she made for the cake walk at her kids' school. She told me she used her favourite and most reliable shortbread recipe.
Last fall she made these fun snowflake cupcakes!
For those readers in the UK I am not sure these cutters are available here- will have a look next time I am in Hobby Craft. They carry a lot of Wilton brand stuff. Joann's in the states is where these are available or probably any other reliable baking store or site like this one!
