I'm not sure if some of you are aware, but up until recently most of my work was with purchased patterns from Adams Leather Works or JLS Leather. My hat's off to these two for their ability to design patterns and offer them to the public, either free of charge or a small fee. I'd highly recommend either of them to someone that is just starting out or has difficulty drawing their own. Stitch lines, I felt were my biggest obstacle up until the light bulb finally turned on for me. Once I figured out how to measure stitch lines, I used JLS' printable instructions for basic pattern design. These helped me with the basic fundamentals of the top line and belt slot placement. So many people design holsters with too little grip clearance. JLS' instructions will steer you in the right direction. Take a look if you haven't yet.
So, these pictured below are some of my newest that I consider 100% from scratch builds. Slowly redesigning everything I have a gun mold for when I have time. Of course, my favorite, the 1911 is due up first.
