The leather
Why the atelier examines the leather first
A fur is hair carried by a pelt. It is this pelt, the leather, that holds the seams. As long as it stays supple, it can be resewn, repaired and altered. When it dries out, it becomes brittle and splits along the seams. That is why the condition of the leather decides everything, before the look of the hair.
The first gesture is simple: fold a section of the garment between your fingers and listen. If it folds like fabric, or resists a little without a sound, the leather is in good condition. A faint crackle, like paper, signals leather that is starting to dry out. If it crackles clearly, or the pelt splits, the leather is too fragile for a standard repair.
The atelier also looks at the hair (running a hand over it, do hairs stay in the palm?), bare areas, the state of the seams and the lining, and the smell of the inside: a smell of damp or mould signals leather attacked from within. The lining itself can be replaced: it should never be a reason to give up on a repair.
Leather usually dries out because the coat has spent years somewhere too warm and too dry, near a radiator, or on the contrary in the damp of a cellar.
