I want to reinstall cloth on a GC III that i recently bought since it looks to be worn very little. The staple marks on the slate backer show that maybe the table was redone only 2 or 3 times. The question is the best way to restretch since the pocket cuts are already there and the edges have been trimmed so there's no good selvedge to grab. Pulling a bit tighter than original using canvas pliers would seem to be the answer but there's no way to index the pull. I'm very experienced in woodwork and upholstery and have the right tools and equipment and have no fear of screwing up but if I do I'll certainly hire a professional mechanic to install new cloth. Should I give it a try? Mitch
