How to Tie the Morrish Mayday

  1. 1

    Step 1

    Mount the hook and start the thread. Wrap back to the bend and tie in a short tail of grey sparkle emerger yarn, keeping it sparse.

  2. 2

    Step 2

    Dub a slim, tapered body of light olive dubbing from the tail forward to the thorax area, leaving room for the wing and hackle.

  3. 3

    Step 3

    Tie in a wing post of grey sparkle emerger yarn at the thorax position. Post it upright with thread wraps and secure firmly.

    The synthetic wing is very visible on the water and won't absorb water like natural fibers.

  4. 4

    Step 4

    Select a grizzly hackle feather slightly oversized for the hook. Tie it in at the base of the wing post.

  5. 5

    Step 5

    Optionally dub a small thorax of brown olive hare's mask dubbing around the wing base. Wrap the hackle 3-4 turns parachute-style around the post.

  6. 6

    Step 6

    Tie off the hackle, trim excess, build a small thread head, and whip finish. The fly should sit flush in the surface film with the wing post visible above.
