Isn't this the cutest card! Melanie Muenchinger designed this card using her stamp set called "Have a Cookie" available from Gina K Designs. I recently purchased a book by Annie's Attic called "Interactive Cards" which features many cards by Melanie. She also has a tutorial on her blog for this card here. The card was very easy to make using Nestabilities, a Cuttlebug embossing folder and Melanie's stamp set.
