I seem to have this problem more with feathers that I have had for a few years.
I also wrap the herl around my tying thread. The thread is barely noticable if you use 08 thread.

" Fishermen, hunters, wood choppers, and others,
spending their lives in the fields and woods,
in a peculiar sense a part of Nature themselves,
are often in a more favorable mood for observing her,
in the intervals of their pursuits,
than philosophers or poets even,
who approach her with expectation."
Henry David Thoreau
