Looks fantastic. My sewing skills limited to button replacement. I think I will take your pics and my seat(s) to Tim Pearson at Triple-K upholstery in Welland, ON (Canada). Only thing I might add is a gel-pac . Tim 'fixed' my Blackbird seat with a carve + gel-pac job and did an "undercut" on my K1300S (which he calls a Sea-Do seat, where the foam is attached to the pleather cover vs the seat pan) to get rid of the miserable 'crown' in the center of the seat. Great post! J
