I have a couple of heavy wooden clipboards that I use to tape down watercolor paper before I saturate it. Because this paper was thinner it warped quite a bit as it dried even though it was taped down and allowed to dry completely. What I do when this happens is use red liner tape to adhere it to a heavy card stock piece and then trim down as needed.
