Hi John,
I have not created a video course for creating new leather Bible covers. It is something I have been thinking about. The trouble is that it takes quite a few specialized tools and skill to work with leather. In order to simplify what I know I would have to change it into something different so anyone could do it with only a few tools. Paring leather is just hard to do without lots of practice. It is all about sharp knives.
I am not on Patreon. I appreciate the wish to support me. Becoming a member (getting the All-access Pass) is the best way at the moment. Maybe I should create a $4.99 / month support membership? Or just a "Buy Sophia a cup of coffee" button. I do drink a lot of coffee!
In any case, it sure makes my whole week to know I am helping someone with my efforts. Cheers!
