This was a really fun project for the kids last year. They like to get in on the Halloween decorating. We used Elmer's glue to stick google eyes of all different sizes to our family photos. It was so much fun we can't wait to do it again this year!
Another easy project we did together involved candy so they loved this one. We searched "vintage Halloween labels" on the Internet and glued them to my jar collection filled with treats to create a Deadly Sweet Shop.
