Maybe that's where I'm coming from but is anyone, except me, interested in promoting a "subculture" that devotes itself to fly recipes that use no synthetic materials. A singular exception might be the thread, nylon vs silk. My thesis is probably based on my age since I started tying right after
WW II, before there were synthetics. A theme could be: "If the material never walked, flew or grew on the ground you can't use it." (smile)
