Carl - Yes my wife knows, and no the hosiery was not mine. Honest.
I was reorganizing my fly tying desk today, putting away all the materials from my tying demonstration. I found a long forgotten box of odds and ends (assorted textile materials), that I had never gotten around to using. A couple years ago, my wife was throwing out an pair of pantyhose and I got the bright idea that the material might be a useful tying material or could be used to make egg sacks for fishing. I snipped off one leg and stashed it away for later use. The material is very stretchy, glossy and semi-translucent. Characteristics the seemed like good fly tying material.
I clipped a small rectangle of the material and gave it a firm pull, expecting it to unravel. To my surprise, it stretched out to about three times as long, and formed a small round strand. Hmmm...this looks promising, I thought. I then cut another piece, into a tapered trapezoid, figuring that I could make the strand thicker on one end, augmenting the taper of a caddis pattern.
Then I started playing around at the vice, to see how it worked. These are my first attempts.
I decided to use two starling feathers and forego the thorax of the fly. The starling feathers are very light and fluffy, which should give this pattern a lot of life in the water.
All in all, I am quite happy with this fly. (plus I got to play with ladies hosiery...win-win
