There seems to be a little bit of a wall we hit as far as patterns go. I know I did. I take a look through sites and see a design then try to draw it...then it comes out wrong. I start to over think it then get frustrated.
Anyway, one way I've found to cope, so to speak, it to take the previous holster, then adjust things about it that I did not like. Shape, length of belt loops etc. Basically trying to improve the fit of that particular pattern. Hopefully when it's done, it comes out a better version of the last. After that is right, maybe go to the next pattern. Or if that patter is money, maybe do it for a different pistol. Anyway, just an approach I am trying. YMMV.
