Pumpkins on a board

Plastic pumpkin treat buckets can often be found for around $1 each during the Halloween season. Simply screw them to a painted board, place a light inside each pumpkin, cut a small slot in the back for the wiring, and glue a plastic orange plate over the top opening.

The finished prop is inexpensive, easy to build, quick to set up, resistant to wind, and stores easily between seasons.
