All of the feathers are hand painted imitations I painted the red shafted flicker ones.
It is backed with a piece of brain tanned buffalo tipi skin which gives it body.
One original (shown in the enclosed photos) shows it being back this way as well.
It may not be evident to some, but IMO the reason for that is when riding a horse on the windy Plains, an unbacked piece of wool with feathers will get all twisted up by the wind or the motion of the horse.
I did not make the axe head, but had a friend make it for me based on an original. Ax head by Iron John Logan
