If you want a truly original pumpkin, your best bet is to generate your own pattern. This downloadable software will create a carving pattern from any digital image or graphic, including logos, pet portraits, monograms, and just about anything else you can upload. Just load the image file into the software, then crop, rotate, flip, and even morph the image to your liking. Follow the prompts, and in a few clicks you'll have your stencil and instructions on how to use it in hand.
