I only recently have bought whole peacock tail feathers for my fly tying. I found that the ones that were already plucked and sorted into bags had a tough time wrapping at times, as they were already kinked up.
Yes, I know: Fly tying can be quite OCD-like at times. In the case of herl, I want the fibers to fold “just so” on some dry flies, particularly so when they’re small. I’m glad I bought the whole feathers, and I’m particularly grateful for the video.
Have a look at it. It’s awesome!
