how about getting a piece of masonite or wood that would fit on your dining table? Have it cut, add some knobs or feet to the bottom to keep it from scuffing up your table. staple a layer of batting and a top layer. I have used ironing board fabric (the silver stuff), cute novelty fabric but my fav is white or off white cotton duck. You can store it behind a door or under a bed. A handle that is not as deep as the feet would make it easier to pick up.
