I forgot to post the shoes I made last August. They work alright. I made the goat bark tan leather too.
This style is based on an old Anglo-Saxon design found in York from the 10th century. They have vibram soles though instead of being a turn shoe.
I learned to make them with Jason of Laughingcrowe.com. He has videos available on how to make turnshoes.
If you see me in person I can teach turnshoes and the style pictured (which Jason calls “internal stitch down”). I have the tools and leather.
