Tying instructions

  1. Secure the jig hook in the vise.

  2. Start the thread at the midpoint of the hook shank and wrap rearward to the bend.

  3. Cut a piece of red ultra chenille approximately 1.5 times the length of the hook shank.

  4. Tie in the chenille at the bend of the hook, leaving an equal length extending beyond the bend.

  5. Wrap the thread forward to the midpoint of the hook shank.

  6. Fold the chenille forward over the top of the hook shank and tie it down at the midpoint.

  7. Create a small thread head at the tie-off point, whip finish, and trim the thread.
