Here is the piece that I chose to use. Since it is out of the norm for me since there is no tooling involved, it took me a while to figure out what design I wanted to use. I laid out my pattern and drew a pen marking of the final size. I the cut the piece out leaving about 1/2 inch all around. Using my pen marking, I used my C.S. Obsorne skiving knife and just inside the line, I started skiving the leather outward to a paper thin size (I have to thank Peter Main) for showing me how to properly skive leather. Now to the corners so they fold properly and then a stiffener.
