“Feelers” and Latin have gone hand in hand with one another for the last half century. Each time we get enamored over insect science via the teachings of some new prophet, we tiers feel compelled to add them to everything that floats, sinks, or simply drifts fetchingly between the two …
… and us fishermen think the idea is doubly grand until we get the first pair intermixed with our Clinch knot and sever both of them with one great yank and the oath to match.
Ditto for counting tails and matching the real insect fiber for fiber.
What’s not shown in Fly Fisherman, is the editor received the flies in a padded envelope where they were hooked into a business card and mussed, and the fellow that dreamt the concoction had them tucked into his fleece path for a fortnight …

Figure 1: Feelers tied in and forced upward due to material under them.
So those beautifully draped feelers that follow the curvature of the hook shank are as artificial as Pamela Anderson’s better half, and now you’re mouthing obscenities because you can’t reproduce either pert or up-thrust.
Use the Ribbon-Scissor trick to induce a more concise and compact edit of the original, and in so doing, tame any unruly and misguided fibers so they point where intended – versus the drape induced only by a damp fleece.

Figure 2: Feelers scraped over the scissor blade like curling ribbon
Simply anchor the feeler fibers well with thread, put the scissor blade under the feeler and press the material against the edge with your thumb. Pull the material over the scissor edge like you were curling ribbon to induce a light or heavy drape to the fibers. Repeat until you’ve got the curvature you desire.
Magazine and book plates don’t always reflect the abuse the fly has received, especially on older flies that may have been fished many times. Us poor tiers are left to guess what elements were made by Man and which were caused by misfortune – and it’s not always obvious.

Nearly twice a year I’m required to join the rest of society for a weekend of normality – foreswearing hooks and tinsels, muddy creek bottoms, mashed sandwiches, and foul language.
After the bird is scalped these feathers hang forgotten for a couple decades until moth damage requires someone replaces their supply of Royal Coachmen tailing – by then the golden crest is warped into a number of odd directions which we hope will tie flat but know better. 
There’s nothing better than Science that fits a puzzle piece exactly into an odd shaped void of unexplained phenomenon, making our lives that much more meaningful …
I find it compelling drama but as it’s occurring in Europe there’s hardly a mention of the issue in our media.
