I had my husband cut out a board that is big enough for a fat quarter to lay on, or just about, and a little wider. I don't have any batting that can take heat, so I used several layers of fabric (I think I did), and made a pillow case out of muslin. I have it on my ironing board, and it is very stable there. I love it. You definitely need something stiffer than an ironing board. If I had the room, I would but my made up board on a table, but I don't. I can put my regular ironing board right where I sit, lowered a bit, and then the made up board on top so it is very convenient to turn and press. I thought, you know, I hate to iron. Why did I take up a hobby with so much ironing? Oh, and I use steam, too, but haven't had a problem with the board warping, and I have used it quite some time now.
