I'm with SewGood and have a board built to cover my ironing board. It's 18x49" and I covered it with layers of batting, foil, and heavy smooth fabric (I don't know what it is, but it's from the upholstery department). Everything is stapled to the back, so there's no washing or changing but I can wipe it down and it's held up for years. My husband fastened strips of wood to the back so it "holds on" to the ironing board. I love the ease of pressing yardage on it. My only complaint is that some of my iron cord is rusty red as it has picked up colour from rubbing against the board. I think I'll take a page from SewGood and look for a ham just in case I want to iron clothing.
