iPhone App Idea

This is a real simple one I'm assuming, but it eludes my grasp of software development. Here goes. I don't have an iphone but if I did I would use this app. You can either upload a photo to the app or take a picture with your iphone and what the app does is make a real paper mask of the person whom you take the photo of. Similar to the app that turns photos into real postcards that can be sent. This app takes a portrait photo and removes the eyes and you can choose to have the mask be held together with an elastic band or held up with a small wooden stick. It would sell for maybe $1.99 and shipping would be included if you order a certain amount. But picture it, personalized masks that can be worn for a friends birthday party, sporting events, school projects, bachelor parties, etc...
