Oval tinsel Gold oval tinsel (Medium French oval, serving as both tag and rib)
Floss Fluorescent (hot) green floss (One length, doubled for the tail plus three passes for the body)
Squirrel tail Natural deer hair (A stacked, sparse bunch for the wing)
Saddle hackle Yellow (chartreuse also works) (One feather for the collar)
How to tie it
Start red thread on a size 4 single salmon hook and tie in the medium gold oval tinsel at the rear. Take a few turns as a tag, then leave the rest of the tinsel attached. It becomes the rib later. This saves retying.
Cut a length of the fluorescent green floss, double it, work it back to the tie-in point, pinch it up and trim it so the tail extends just past the bend of the hook.
Tie in the floss for the body, run the thread back to the bump at the rear and forward again, making three thread passes to fill out the rear of the body, which should look bulbous.
Make three passes with the floss: the first fills the gap at the rear, then work forward and back and forward again, crowding the turns so the body is smooth, thick and completely opaque. Three layers stop the red thread bleeding through when the floss gets wet.
Tie the floss off with a few extra turns and drop in a half hitch.
Wrap the rib: take one pass right at the back to make sure no red thread shows, then spiral it forward evenly and tie off.
Stack a sparse bunch of squirrel hair and tie it in as the wing, reaching to just short of the bend. Keep it sparse, a bulky wing makes the collar hackle very hard to wind. Trim the strays.
Tie in the yellow saddle hackle, pushing any forward-pointing barbs back, and wind a Cosseboom-style collar in front of the wing. Tie it off and trim.
Build a deliberately bold red head with the thread, whip finish and add head cement.
