Using foamboard for a backdrop I would make long pins for the foam to slide over. you would need some heavy music wire and have to pre drill the base a size smaller than the wire, then use needle nose pliers held close to the base to force it into the hole. You can buy construction flags that are on stiff music wire at most big hardware stores. This wire would work and the flags are approx. 18 inches. You would have to be sure the wire holes were perfectly vertical, then slide the foam down over the wire.
