I am into a moccasin battle with a friend ovr the fringe. I hav always thought and believed that the fringe’s purpose was either purely decorative or to provide motion to keep flies away. He says that it because on the knee high moccasins that was how they put the shoe together, by tieing the fringe. i hav never heard of tieing the fringe in my life and i hav asked several people and i hav been to an indian artifact museum and saw nothing of the sort. Please inform me on whether the fringe was purposed for embellishment or ”tying” the shoes on. thank you
