Rough carved edges can be trimmed smooth again, so don't worry if your monster's smile comes out a little jagged. (Frankenstein is a little rough-around-the-edges by nature, anyway!) We use a triangular-headed clay-modeling tool to touch up uneven edges; just skim the tool along the surface edges to trim away irregularities. (Another clay modeling tool, known as a trimming loop, will do the same job.) We keep a large trimming loop on hand to scrape the inside walls of the pumpkin, and a small trimming loop can be used for detailed carving touch-ups.
1. Clean your pumpkin by sawing a circle in its bottom and removing all the messy bits. Scrape the side of the pumpkin that you're intending to carve to about 1" thickness. (Hint: Carve the flattest, smoothest side!)
2. To transfer the Frankenstein pumpkin stencil to the surface of your pumpkin, tape the stencil to your pumpkin and poke tightly spaced holes along the pattern lines. Remove the stencil.
3. Carve the pattern by using a small, thin pumpkin-carving knife to saw along the pin-hole cutting guides. Pop out carved sections by pressing on them from inside the pumpkin. Touch up any rough carved edges by following our tips above.
4. Place a votive candle or battery-operated tea light inside your pumpkin to set Frankenstein's face aglow.
