If lighting a large pumpkin with mini lights, wrap a glass jar with a strand, securing one end to jar with masking tape. To light a small pumpkin, arrange strand's bulbs into a bouquetlike bundle and place wires in a glass jar or ramekin. Use a 25-light strand for small and medium pumpkins, and a 50-light strand for larger pumpkins. If using lights, place jar on reserved cutout base of pumpkin, then place pumpkin over lights. (Make sure the lights don't touch the inside surface; this can be a fire hazard.) Secure base cutout with T pins. Once the pumpkin is lit, you may want to do a few touch-ups: If the light shines unevenly through her face or the moon behind her, the flesh may be thicker in some spots; simply scrape away a little more wherever it appears darker. When finished, place a few candles and dark "potion" bottles around the pumpkin for an extra-creepy effect.
