How to tie it
Lay a base of black 70-denier thread on a size 12 1X-long nymph hook.
Tail: tie in a pinch of partridge (or guinea) fibres at the bend, about one hook gap long. Leave the butts a little buggy; the rib will tame them.
Rib: catch in the oval gold tinsel at the front, pull it back along the shank and bind it down, then run the thread back to the tail.
Body: dub the seal fur onto the thread in short noodles and wind forward, stopping short of the eye to leave room for the wingcase and thorax. It will look messy; that is expected.
Spiral the oval gold tinsel forward in fairly close turns to bind down the loose fur, tie off, and trim any stray fibres that still stick out.
Wingcase: fold the Swiss straw over once more to narrow it, and tie it in on top of the shank just ahead of the body, checking it sits dead on top.
Thorax: dub another small noodle of seal fur and wind it in front of the wingcase tie-in.
Fold the wingcase forward over the thorax, take a couple of wraps to secure the end, one more in front and one on top, check its position, then trim the straw as close as you can.
Legs: fold the fibres of a small partridge feather back, snip out the tip to leave a small triangle, and tie the feather in by that tip with the concave side toward the hook, two or three wraps, then fold the stub back over itself and secure. Wind one and a half to two turns with hackle pliers, tie off, and snip the excess.
Preen the fibres back, build the head from just behind the eye ramping rearward to capture the stub ends, whip finish, and add a drop of head cement.
