I need a large ironing board. I have looked on line for one but they seem to be rather expensive. Also saw many plans for making one, but I have absolutely no talent with saws and such and directions call for a furring and I have no idea what that is. I was thinking of buying a large piece of plywood that I could cover and just set on top of my cutting table when I need it, rather than trying to fit one to my existing ironing board. Has anyone tried this?
