My mother-in-law came over for a morning a couple weeks ago and let me get out of the house alone. When I came home, I found the kids running around in these spider hats. They looked pretty simple to make. She used some bulletin board border she had for the top, but I'm sure black construction paper would work just as well. The legs are just folded paper stapled on and the googly eyes are glued. The kids loved making them and chasing each other around.
