Get some round paper lamps that are battery operated from a garden store or garden area in a store like garden ridge or world market. Wrap with spider web cotton and put spiders on it and hanging from it. Can paint bulbs with glass paints from a craft store like michaels or hobby lobby to give a color you want when you turn the battery operated light on. Hang them around the yard from trees, in front of windows, over doors, in house. Can also use snakes or rats instead of spiders or use all. One big spider wrapped around the whole globe would be cool. Can use black light webs and spiders and have black light on them. Have some blood dripping from the cuccoon. Can include those fake hands, etc. coming out of the cuccoon like the spider wrapped them for lunch!
