Calf (Kip) Tail is a very useful material with many applications in tying dry flies, streamers and bass bugs. The yellow calf tail I show here is what I use to tie the wings of the Mr. Rapidan Dry Fly series. The space between the two pencil-pointers gives us the hair which is easiest to make nice even dry fly wings. I hold these hair fibers by the tips and brush out the short, useless hair and the fuzz with an old tooth brush. Usually these hair fibers are even enough to tie in as they are producing nice straight wings. If you like you can straighten these hair fibers in a hair evener, but I seldom find this necessary. The long hair fibers on the tip of the tail make excellent streamers, bass bug tails and even sometimes wings for Trude dry flies. These come in many dyed colors and are inexpensive. The more you experiment with these in your fly tying , the more great uses you will find for them.
