I recently bought a Bentley continental gt that, like a lot of these classic sports cars , had a sagging roof leather lining. I’d had Amish upholstery specialist recommended by a friend who enthused about their precision hand stitching and work on specialist cars. I left it with them for two days and they completely removed the roof lining and using special heat and cold glue refitted it leaving the roof lining looking brand new. No blemishes, no stretching just immaculate work. Highly recommended for all types of upholstery car or furniture great workmanship .
