Randy,
The straps are all 54-56" long which should be more than long enough for the tallest and widest folks. I am about 5'-10" tall and almost as wide and all the pouches sit on my hip or just above. That means that most other foliks would want to shorten the strap. The way you do that is just punch/cut two new button holes at the correct location and cut off the excess strap (if you want). You can shorten the woven strap about 8". The leather straps can be shortened pretty much as much as you want.
I used two buttons for the adjustment for several reasons. First, the period documentation mentioned two buttons. However, it was not clear as to the arrangement of the buttons. For the woven strap and the two-piece leather strap, you had to put the buttons where you would normally put a buckle. I guess I could have used one button here, but one button would allow the strap to swivel around too much and, in my mind, be too weak an attachment.
With the buttons on the pouch with the one-piece leather strap, you have two choices to be in aggeement with the period documentation; two buttons on one side or one button on each side. In light of ambiguous evidence on the original pouch, I went with two buttons on one side for reasons of strength. I may change my mind with further study and was hoping for some feedback from others on this.
Thanks,
Mark E.
