Thanks chief...
The drawing was submitted by the customer so it's probably just conceptual. I'm not sure folding the gusset accordion style would even be practical as the purse is intended to just carry the gun in the rear pocket, and a few things in the front.
The few purses I do build are more primitive mountain man, or possibles bag style. I actually have my own ideas on how to do the job, since I do a bit of leather work, and do carry a gun. But it's sometimes very difficult to change a persons mind.
I appreciate the input.. Regardless of the folds in the gusset, I'll probably do just as you suggest. I doubt the threads showing will be an issue..
Regards, and thanks again!!
