Here’s another caddis design that I find exceptional. Others have fished it with shot like a nymph, pulled it under and fished it with a rapid retrieve, and many other ways. It’s one of my favorites for the Down Dry/Up Wet tactic discussed in Fishing the Film. All you need is some deer hair and a little dubbing. The illustrations are by Jason Borger, taken from my book, Designing Trout Flies (1991).
Wrap the shank eye to bend and back with thread. End with thread about 3 head spaces behind the eye (one head space = length of eye). Tie in a clump of deer hair with the tips pointing rearward just long enough to form a short tail on the fly. Secure the clump tightly at the front and then spiral the thread rearward and secure the hair tightly at the rear of the shank. NOTE: at this point, stop and add the body dubbing to the thread, leave an inch or two of bare thread between the hook and the starting point of the dubbing.
This is what the fly looks like after the hair is secured front and back.
Grasp the butt ends of the hair and fold the clump tightly back over the top of the body. NOTE: don't let go! Use the thread to secure the clump tightly at the rear of the fly. When the dubbing reaches the body, wrap it forward to secure the deer hair of the body. NOTE: Keep a good grip on the butt ends of the deer hair all this while.
Once the dubbing is in place, fold the hair forward over the top of the body and secure tightly at the head. Clip the butt ends of the hair to about 1/2 the length of the shell back. Coat the back of the fly with several applications of flexible head cement.
