Glue magnets to the back of spiders and put on front door. I bought about a hundred plastic spiders from the target cheap-o section for $2.50. Then I got magnet "tape" from Joann Fabric for 80 cents. Hot glued the tape to the back of the spiders and voila! Really creepy halloween door. These babies are going to be scattered around our halloween wreath on the front door this year!
