1. Grasp wingcase with right hand and pull forward.
2. Hold wingcase with good tension as you make a loose wrap of thread.
3. Notice how wingcase is still straight forward. You may want to angle it toward you a little so that when we tighten thread, thread torque doesn't pull case material to far side of shank.
4. Use two or three wraps.
5. Tighten thread. Let the thread pressure bring the wingcase material down to the hook shank, this keeps material in a neat bundle on top of shank.
6. Maintain thread tension and add 4 or 5 more wraps.
7. Cut excess wingcase material so that head is around 1/2 of body length.
8. Now ready to tie-in rubber legs.
