Instead of a drawstring top, this time I used my snap pliers and snap set to make the pouch strap adjustable.
My assistant came around to supervise the project...
I just sewed a small rectangular pouch and added a strap
Then, I added a snap to the strap and two places to snap the strap onto for adjustable lengths.
(don't mind the white thread... I probably should have switched it to black, but just didn't care enough at the time :) )
