If anyone is looking for a professional sail repair specifically stiching that has come undone, contact Kevin Greaves at 801.599.3582. I had to repair my mast sleeve at the base and Kevin did a fantastic job for an incredible price.
He has done repairs before on sails and i'm really happy with the outcome. He gave the ok for the address to be given:
1899 s. Redwood suite A9
Thanks Kev
