Mount a standard dry-fly hook and start cream thread a third of the way back from the eye.
Cut matched slips from a pair of grey duck quills, pair them concave sides together, and tie them in upright, one shank length tall.
Post and divide the wings with figure-8 turns.
Wrap back to the bend and tie in a bunch of ginger hackle fibres as a tail, one shank length long.
Tie in a stripped peacock quill by its tip at the bend. Soak the quill first so it does not crack as it goes round the bend.
Wrap the quill forward in touching turns to the wing so each turn shows a distinct dark and light ridge, then tie off and secure with a drop of cement — a quill body is fragile and this is what makes it last.
Tie in two ginger hackles behind the wing and take two turns behind and two in front.
