With tape, attach the triangle strip to the circle. *To attach the hat to the eggplant, place the hat on top of the eggplant and stick 2 toothpicks through the taped-down hat strip, on the backside of the hat.
Witch's Broom: Cut a broom's shape out of brown paper. Then use scissors to cut the broom head strands. *Attach the broom to the eggplant witch with a toothpick OR make arms out of toothpicks and then tape the broom to an arm.
