I have one of those big boards that fits on top of your regular ironing board. Love it! When the covering that came with it got nasty I made a "sandwich" of batting, insultbrite and then topped it with that silver coated ironing board material. Turned the board upside down, clamped all the layers nice and taught and used thumb tacks to attach to the board. It's nice and smooth and the insulbrite helps reflect the heat back up through the top covering.
