If you are planning to carve pumpkins this year, you might want to stop by the Better Homes and Garden website to check-out their free pumpkin spencil patterns [2]. The patterns are downloadable as a PDF and available for you to print.
After you print your stencil you can blow it up on a copier or use it as is by using a pin to trace the outline onto your pumpkin!
