I down loaded a free pattern pack from tandy leather. I felt like it was too small for me. I wrapped a sheet of paper around my arm and sketched some cut lines. I did stuff my original paper pattern under the bench. I will dig it back out and get a pic.
Tandy pattern on top. If I was to start again, I would use the tandy shape. I would follow the same lines on the sides, but extend it out on the elbow end. I would also probably shorten the wrist end to make it wider, following the original lines. My pattern on bottom.
A quick holster that I made this morning for my dad's birthday. I hope it fits something, I just made it kind of universal.
