What a cool fly !!!!
I do not fish for carp. However I frequently use the twisting technique to create a tail.
I prefer (especially when tying with the longer eyelash yarns) to twist the yarn in a clip (such as a bulldog clip found at office supply stores). I then remove the twisted yarn from the clip and tie in to the hook. With the eyelash yarns I find it easer to keep the "eyelashes" from getting caught between the strands when I work with the yarn pointed towards me.

" 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
