I purchased 2 large pieces of foam board 4x6. Cut each piece into 4x3 pieces and taped the front with clear shipping tape so I can fold. Cover the front with flannel. I hang them on my curtain rod with pant hangers or I can lay it across my bed. It's lightweight and very portable. About $30.00. What is nice about it also is that I can adjust the size. I purchase another piece at a yard sale for 1.00 but will cut it down to size. It will adjust to a king by the time I'm done.
