How-to Carve Pumpkins Using Cookie Cutters
Before you begin, carefully cut a circle around the pumpkin stem, lift off the lid and remove the seeds from the lid and inside the pumpkin. Place a cookie cutter on the pumpkin and firmly with a rubber mallet until at least half of the cutter has pierced the pumpkin's shell. (If the pumpkin shell is thin, the cutter may be pounded all the way through the shell.)
Remove the cookie cutter, using a needle-nose pliers if needed.
With a small serrated knife (or the serrated say from a pumpkin carving kit), follow the pattern made from the cookie cutter to cut out the image, making sure to cut all the way through the shell.
With one hand inside the pumpkin, push out cookie cutter image from the pumpkin and discard.
