This vest has seams, edges, lapels, back yoke, pockets, etc. done with leather braiding with top quality, full grain moccasin cowhide. The 1/4" wide laces that it is braided with are cut from the same leather that the vest parts are cut from.
Over the last 40 years, I've custom built hundreds of vests - you can see over 50 of them on my vests home page. While they are all braided, that's pretty much where their similarities end. After seeing the many features I can offer, folks contact me with their own ideas/designs and we discuss how I should build one for them. Each vest ends up truly being a unique, handmade, long lasting, one of a kind piece.
