After they were wearing their "costumes," each guest was given a red visor, purchased at a craft store, to decorate. I printed clip art of the different members of the Incredibles family and used spray adhesive to glue them onto colored sheets of sticky-backed craft foam. I them cut out the images. The kids simply peeled the paper backing off of the characters and stuck them on their visors. They looked really cute in their visors, t-shirts, and masks!
