Idea for the graveyard. Create a ghostly specter floating above a tombstone by mounting a hand to the top of the headstone and installing a pole-mounted upper torso and head with lightweight sheer curtain fabric one foot behind the tombstone. Put a cheap fan in a weather-proof enclosure at the rear base of the tombstone and aim it toward the fabric. Light with a UV LED light.
Halloween Grave Stones. *make your own grave stones. i did these last year! :) it was so much fun to do and easy!! i bought my styrofoam in a pack of three long sheets at Lowe's and then just used black spray paint and a bottle of black puffy paint do write on them! :)
