First, Thank you to OzHaggisHead for the instructions and pattern.
I had a pile of scraps from an upholstery side laying around. So using the instructions posted by OzHaggisHead (Instuction link) and the scraps, I made something serviceable. And being from scraps, I was mainly looking for experience and not total perfection. I think I did an ok job, what say you?
Front:
Back (Oz used heavier leather and slits for the belt loop. With the thinness of the scraps I had, I used a 2 inch wide by 3 1/2 inch long piece of nylon webbing):
Inside front (again, the scraps were thin, so I reinforced the top with a piece of 3 oz Latigo):
