I picked up a couple of square feet of bookbinding leather. The stuff I bought is referred to as 1.5 oz. leather. The "sheet" I got averages right at .015" thick. I was looking for something to use for the upholstery in my Supermodified. My idea was to use basic leather-tooling techniques to create an upholstery pattern. For the test, I used the brass strip and ball-peen hammer in the photo. I merely eyeballed the pattern for the test. There are several areas with a finer grain than pictured, that I can work with. I really think it has some promise!
