I am researching making a shooting bag. I have a general idea of the pattern I want to use. I have some leather that is two to three ounces but is very stiff. If I sew it together inside out, I am afraid it will be to stiff to turn the right side out. I have two questions. Should I soften the leather before sewing it? And what is the best methiod of softening the leather before I sew it together? Thans for your help.
