Does anyone have any experience with quilting patterns onto leather, for example for the front of a handbag? Can you do this by hand or would you need a sewing machine? Looking up some info online it seems you would just need a fine leather, some foam and lining to do patterns like in this example (which is a cannage pattern from Dior but the idea would be to create other pattern shapes)? It would be very nice to have a masterclass course that demonstrates this technique in more detail.
