I can't say about Columbia, but I do happen to know someone who does sail repair in the Raleigh area.

I ended up taking it to a guy that has done some boat cushions and convertible top for me.. It's minor enough, that he shouldn't have a problem except for having to order the material. But, Let me know your guy in Raleigh for future. I did call Joe Waters.. nice guy and probably would have used him if the logistics would work out. I would like to get it done before I head to Columbia though...
