I appreciate the picture when you get one, I am having a hard time seeing it in my head. I have an idea but always good to see it for me.

What I have done with hackle in the past is to take 2, cut them same length, lay them in a 'v' pattern over the shank and the bend of the hook for a tail look. Probably not the best way but is the way I did it from seeing other patterns made.
