To remind the girls of their Holy Ghost lesson (and because it was Halloween time), we made these Girly Ghosts.
Cut a dinner-plate sized circle from lace (I used scrap on hand; you could buy a remnant for cheap from the fabric store). Wrap it around a 1-1/2" styrofoam ball and tie at the neck with ribbon to form the head. Glue on eyes and attach sparkly stickers and bows. Push a floral pick into the top of the ghost's head and thread a length of ribbon through it to hang the decoration.
