Just had my E22 seats and motorbox re-stitched. Did all of the bow seats, the motor box cover and the back middle seat (back rear seats had been done a few years ago). Also had an observer seat skin I bought from Captain Rick installed -- all for $600 bucks. This guy works out of his house in West Houston and uses Kevlar thread. Says it should last for the life of the boat. My surf interior looks brand new for wayyyyyy less than a new upholstery job would cost. If you're close enough to Houston to get your boat here, I'll be happy to PM you his contact info.
