Melt small amounts of chopped vanilla- and chocolate-flavored candy coating in separate containers. If desired add orange, green, violet, or yellow paste food coloring to the vanilla candy coating. Insert a wooden skewer into one end of your favorite creme sandwich cookie. If cookie begins to open too much add some melted candy coating to the inside of cookie sandwich, press together around skewer, and chill in refrigerator until firm.
Working with one cookie at a time, dip cookie into melted coating, covering completely. Transfer to a parchment or waxed paper-lined cookie sheet. While coating is still soft, decorate with small candies and nuts making ghosts, skeletons, witches, pumpkins, monsters, mummies, and owls. Chill in refrigerator for 10 to 15 minutes or until coating is set.
