Steve, I found a good firm strong silver canvas for redoing the seat. Found it at Sailrite.com. I thnk it is UV and rain resistant--kind of like Sunbrella but a different manufacturer. Ask Matt at Sailrite to lead you to it. They will send out samples for you to consider--just a buck or two or so. Used this canvas here, have it on the tractor and like it. Too bad I wasn't a better worker on making it wrinkle free. But my behind ain't complaining. The step-by-step instructions here on the forum are good. I had to add the brass grommet per my design, and that worked out okay.
