my ironing board for quilting is the smaller plastic fold up table. i believe it's 2 feet my 4 ft., about. i covered it with a piece of batting, then a piece i had used to practice free motioning on. so the sandwich was complete. just binded the edges, then pinned it to the 4 leg supports. easy to take off and wash that way.
i believe i paid $25 for it 5 yrs or so ago.
