I was kind of thinking of cutting it down and using the center part that isn't so worn. I can cut it with a jigsaw. Not always real neat but I can sand it even.[/quote]
Cut it with a glass cutter and you will not have to sand it at all. If you don't have one, take it to a store that cuts glass for windows and ask them to cut it for you. Most will do it at no charge or maybe a dollar for thier 5 min of time.
