Realizing that most of you folks tie flies for stream and river fishing, and I tie all saltwater flies, the principles for spinning deer hair is exactly the same with exception of the size of the bug. A few important tips must apply.
1). Never wrap the shank of the hook with thread under the area you are going to spin the hair, it will cause the hair to bind and not spin properly.
2). Brush the under-fur out of the base area of the tuft of hair you clip from the skin side of the patch. By not doing so, it will cause the finished fly to absorb water and sink below the film.
3). Install the clump of hair parallel to the hook shank and make two loose wraps over the hair, then draw the thread down slowly as you release the hair, then wrap the thread with increased tightness causing the hair to flare and spin on the bare hook shank.
4). Using a zig-zag motion, work the thread through the hair as to not cause crushing the spun hair. Then pack tightly toward the bend of the hook.
5). After completing step 4, make two half-hitches tightly against the spun clump toward the eye, and secure with a small dot of Sally Hanson’s Hard As
