Belt reinforcement.

Hi all, I’m relatively new here. Fully enjoying the video tutorials and having a blast learning the basics! I wanted to ask what was the most ideal reinforcement for belts (which brands). i will be using a mixture of calfskin, croco and alligator (starting with a reversible design using the lovely skins from Tannerie Carriat. This is a scaleable project and one which will be sold under my brand.
