I am a newbie to leather as such I have watched damn near every video on holster making that is out there. I agree with JLS, the Andrews videos are the best I have seen for the amount of knowledge Mr. Andrews gives in building the holster and tips and tricks he has learned in this craft.
For some reason my patterns come out too small or too large.....lol I guess that is the learning part. Screw up and you get to do it again learning from my mistakes. I would also like to find out how to figure the proportions of the 80/20 holster without wasting a bunch of leather in trial and error.
JLS, I have used your patterns as a starting point for the P228-229 and p220 series Sigs and finally have a pattern that fits after a couple of tries. I do appreciate your sharing the patterns.
