Clean plastic gallon milk jugs
Black permanent marker
String of 50 clear low-wattage orange lights (available at Halloween or use any color you like)
Draw silly eyes, nose and mouths (be creative) on the jugs. Tip: Leave the caps on while you do this, so the jugs don’t dent.
Use the craft knife to cut a half-dollar-size hole in the back of each jug (an adult should do this step).
Arrange the pumpkins near each other and string the lights between them, stuffing several bulbs into each of the jugs.
