1. Cut holes in the base of each pumpkin; clean out and carve the pumpkin faces. Cut out an opening in the top of two of the pumpkins, removing the stems as before.
2. Insert the dowel rod into the ground and stack the stemless pumpkins on the dowel rod.
3. Thread the tubular light strand into the bottom two pumpkins, leaving some lights to go into the top pumpkin. Place the top pumpkin over the dowel rod and insert the rest of the strand of lights.
