Select the Dora picture you want to use. Print it on regular paper in the size you want for your pumpkin carving.
Cut off the top of the pumpkin, remove its pulp, scrape the inside clean, and clean the outside surface. Tape the printed picture securely to the pumpkin, flattening it against the pumpkin's curves as much as possible. Using a sharp object (such as an awl, artist's stylus, nail, wooden skewer or ice pick), poke small holes close together along the lines of the image.
When the lines of the image are transferred to the pumpkin, remove the paper. Cut out the design from the pumpkin with a carving knife, starting with the largest pieces.
