Advice I would give, is you and the Interior guy need to be on the same page, very few people I have dealt with know whats in your mind and unless you have a seat upholstered exactly for them to copy and a plan with illustrations etc.
With my first cobra after hours of misunderstanding with a good upholster we used our industrial sewing machine and made the leather patterns for the seat sides to illustrate how they should be upholstered, then after two years of use the sewing in the squab is visible between the pleats which indicates they know virtually zero on sewing basics and how to fold under the tails in the pleat and where to sew.
A friend of mine took his cobra seats in to a wellknown upholster and the squab pleats and back pleats never lined up and the front seat cnrs were square and baggy do I need to say anymore, but this work happens everyday.........!
