I am an advisor for a B.S.A. Order of the Arrow chapter. We have had excellent quality, and service, from Moscow Hide and Fur. Their chrome tanned version, of brain tanned buckskin, is very convincing if you give it a little real smoke, after you have run it through the washing machine, with cold water, and a little Woolite. This treatment makes any fringe much more convincing,especially if you can do the washing, and smoking, after the garment is made.
I have a pair of legging I made years ago, from some of that bright yellow buckskin, that was so popular back in the day. Luckily I made them rough side out. I soaked them in warm water and Rit dye remover, and then did the Woolite wash, and smoke. I have had to show fellow buck skinners many times the shiny inside of these leggings, to prove they aren't braintanned.
