To carve an outline as sharp as those fangs, you'll need a few tricks! We recommend carving shapes from the center outward, and leaving the cutouts in place until you're done. Then just push the cut-out sections from the inside of the pumpkin for a clean finish. A small clay modeling tool can be useful for touching up rough edges.
1. Start with a hollowed-out pumpkin, and select the prettiest side for your design. Tape your printed stencil in place to use as a pattern.
2. Go over the stencil lines with a pin tool, pricking holes through the paper and into the pumpkin skin. After you've completely outlined the pattern, remove the taped piece of paper, but keep it nearby for reference.
3. Etch the areas within the stencil's dotted lines by scraping the pumpkin's surface with a gouge or raking tool. Be sure not to cut through to the pumpkin's interior; you should only peel away the surface skin.
4. Carve the areas within solid lines, cutting through to the interior of the pumpkin. Discard excess pumpkin pieces.
