I also have more than 1 ironing board, in my defense tho, got 1 of them at a yard sale, its a heavy duty one, from the 60's, and was like new, I got it for $1.00....so, had to have it...
DH cut me a piece of plywood, and I covered it with 2 layers of 100% cotton batting, and then muslin, I just set it on top of one of my ironing boards when I need to iron large items...that being said, I also asked him to cut me out one from luann, it is lighter wood, and not so heavy for me to lift on and off....
