We used a box top for the base, and painted it black. We made houses out of bird houses from Joann Fabric ($1 each) and we painted those black and put glitter on the roofs. Parker pained spiders different colors and sprinkled glitter on them. We made a tree out of paper towel rolls and painted it brown and black. Parker made monsters (the 3 in the back) out of toliet paper rolls. We painted pumpkins out of styrofoam balls and painted ghost, and added tombstones in the front. Both kids painted the tombstones and houses.
It took us a few weeks to make but it was fun and is something we can add to years later.
