While it's ordinarily best to find the smoothest side of the pumpkin to carve, a few lumps and bumps would add wizened character to this witch's face. Natural pumpkin features, like rough spots or even interestingly shaped stems, can be integrated into your pumpkin design with a little forethought and creativity.
1. Saw a circle in the bottom of your pumpkin with a serrated crafts knife, making sure the circle is large enough for your hand to reach in comfortably. Use a scoop to remove the pumpkin guts.
2. Choose the pumpkin side you're planning to carve, and scrape the pumpkin's inside wall thinnest on that side (around 1" thickness is optimum). Tape your printed stencil to the outside of your pumpkin, flattening the paper down as you tape.
3. Go over the stencil lines with a pin tool, pricking closely spaced holes through the paper into the pumpkin's skin. Remove the paper stencil.
4. Slowly saw along the pin pricks, cutting gently from point to point. After carving the entire design, press on cutout sections from inside the pumpkin to pop them outward.
