While I have no information to offer concerning turbans made from finger-woven wool sashes, or made from silk material, these types of headwear appear in many old photos of some Central Plains and Prairie tribes, both alone or in combination with a hair roach.
If anyone has any information to offer on this topic, I'd be very interested in learning more.
