I am hosting a 'house shaped' atc swap on ATC World. These little buggers are a TON of work, but are really alot of fun. The shape gives them so much character, and houses are so 'in' right now. I am thinking of using the larger template to make a paper and/or fabric book, the possibilities there seem endless!
This series of cards is staying in my collection, but for the swap I have made several that are very similar.
