So here's a Jack-o'-Lantern pattern of the candidate for President that I'm backing: Ron Paul. Same basic instructions as the original: Click on the image to get it full-sized and print it out. Use pins or tape to secure it to the side of a pumpkin. Then use a Pumpkin Carving Kit from Pumpkin Masters, and do with this as you would do with any other pumpkin pattern.
Happy Halloween! :-)
