Hello,
thanks for your feedbacks.
And yes, the idea is to repair the original seat covers so they last as long as possible, I somehow doubt a modern upholstery could ever get the patina mine has, as well as blending correctly with door cards, dash, etc...
I'm currently removing the cover of the cushion, had done that before on the other seat.
For the backrest, I'm afraid I'll cut the stitching and end up at a proper trimming shop!
Didier.
