I started with the dress die from Memory Box. As you can see, it actually is a short-dress die and I simply adhered it to card stock and free-hand drew an extension to make it a long dress. Using Bitty Dot Paper and the small border die, I cut several strips and began layering. I am very pleased with how the dress turned out - but don't think I'd try mailing it as the little scallops would surely arrive flattened.
