Upholstering the rear wheel arc, does anyone have a method of keeping the upholstery piece even has the seam travels down the arch. I have done this a few times and struggled each time; there must be a craftsman’s way. For now I have the vinyl held in with the back seat and piece of un-upholstered backing. The back seat seam and wheel seam probably should meet and from there travel down the arch. I have seen different kinds of padding behind the vinyl and I believe the original stuff was some very thin cotton batting. I might just glue right to the metal without the pad; I do have some thin foam, but I cannot get a good feeling about how this is going together. cannot seem to post pictures
