Hey I wondered if 2 pieces of chevre glued togheter(1.1-1.2mm each panel) will be stiff enough for a small hand bag?

Salamander you can order directly from the company or email them to give you the contact of the distributor in your country or region.

Vildona is a very thin, almost paper-like reinforcment that is made by Freudenberg. I would contact them directly to order.
