I looked up glue for styrofoam and Elmer's white glue and Aleene's tacky glue (you can find it at Wal-Mart) are supposed to work great. Gorilla Glue was also mentioned and liquid nails, but only for styrofoam. Since I have some white glue and tacky blue here I'm going to try that on a scrap piece to see how well it works.
