Question about foamcore for diorama makersArchived Message

I'm making a wall with a door in it out of foamcore. I cut the hole out for the door, & then I glued paper on one side. The foamcore started curving upward on the side with the paper glued on & now it no longer lays flat. Does anyone know why? And how to fix it so that it lays flat again?
