After seeing a Big Board for $100.00 in a catalog, my DH and I figured a way to make it for far less. That was about 15 years ago and it is still going strong. We used plywood, thick cotton batting and denim weight muslin. Then I used a nice cotton fabric as a cover. It's been changed several times. It is now on top of a dresser, perfect for ironing fabric from selvage to selvage.
