You can watch the making of an Alma in Vernis leather and the making of a NF in the video linked below (skip to 00:19:00). The manufacturing process is definitely high-tech. The canvas and leather are cut with incredibly sophisticated machines and each bag is assembled by a small team of employees. Keep in mind that Louis Vuitton sells around 20 million items each year. Somewhere else in the video you can also watch the making of exotic bags and trunks, which is, of course, much closer to the traditional roots of the company.
So interesting. I can't understand what they were saying but it's amazing nonetheless to watch.
