Turkey wing feathers are also quite useful. On the leading edge of the wing feather are biots, which used either in their natural color or dyed can be used to make segmented dry fly bodies (ala A.K. Best), as well as tails for stonefly nymphs.

"If we carry purism to it's logical conclusion, to do it right you'd have to live naked in a cave, hit your trout on the head with rocks, and eat them raw. But, so as not to violate another essential element of the fly-fishing tradition, the rocks would have to be quarried in England and cost $300 each."

My one wish is that when I die my wife doesn't sell my fishing stuff for what I told her I paid for it...
