I'm not sure that I understand your question, but here are a couple of things to keep in mind. Wrap your hackle counterclockwise always. This way when you are tying it off the thread wraps have the effect of tightening the hackle rather than loosening it. Don't be afraid to grab onto the hackle and pull the post and hackle backwards out of the way when tying it off to prevent trapping fibers in the thread. This may make the hackle look bad, but a few seconds work with your fingers will straighten it right back out. And lastly, don't crowd the eye.
