We made our own spider decorations using Styrofoam balls and wire. It was easy to do, and they make nice Halloween decorations. We painted our Styrofoam balls black and glued on some googly eyes. Using a light-colored marker, we even put a happy smile on our spiders. Then, we cut the black wire (you can get this at any crafts store) and stuck them into the spider's body and then bent the legs so they would be able to stand up.
