So... my FIL has a scrap piece of plywood, 22 X 48 just perfect for my sewing table pressing board. I'm so excited! I use an old mattress pad for the padding, an old sheet for the cover, my DH's staple gun to put it all together and turn it over and .... Wallah! The staples are too long because it's 1/4 inch plywood. It pokes through the cover on the top. I pulled them all out and will have to think on this one a while.
