Yesterday I wanted to tie some wet flies that use wings of white-tipped turkey tail. I went to my local fly shop and picked up a package which contained two whole tail feathers. The flies I was tying were on #12 hooks. To my surprise, it seemed that I could only get a couple of strips out of each feather in which the white tip at the end of the feather was the right size in relation to the rest of the strip. Is this a common problem, or did I just pick bad feathers?
