Ace of Cakes. Have you seen it? Decent reality TV and you might be inspired. They do it all with fondant. That stuff is gross but it makes really cool-looking cakes! :)
This software would make it really easy, but the cost is $200. Worth it?
Note how you can print 2 strips of 4 photos on a standard 4 x 6 photo paper print. One for you, one for guests.
So, I think you would need: A PC, junky and old would be ok A USB web cam (cheap) A photo printer, ink, and 4x6 paper Scissors/paper cutter Rubber cement and markers and a scrapbook for posting/signing
