How bad is it? If it is frayed and a little holey, it will definitely need some rework or a new pattern. If it's just a little faded, try washing it and rinsing in Mrs. Stewart's bluing. This revives the color on many items that look faded. I've also heard that some people use it to make yellowed and aged items white again. I use this to make my work shirts a dazzling white as a bleach alternative that won't harm fabric. It's only a few dollars a bottle and it wouldn't hurt to try.
