Mount a size 4 7X-long streamer hook and catch in black 70 denier thread up front; there is no need to take it to the back yet.
Tie in large mylar tinsel with the silver side toward the hook so silver shows when it is wrapped, then bind it back with open wraps to just around the bend, as far back as you want the tag.
Bring the thread forward to about the hook point and park it with three big loose wraps out of the way, then wind three turns of tinsel at the rear for the tag. Back the loose wraps off and catch the tinsel with two tight wraps behind and one in front.
Take the thread to the front and tie in a long piece of red floss, ten to twelve inches. Wrap it back to the tag and then forward again for at least two layers, because floss goes translucent when it is wet and one layer will show through; catch it off up front.
Rib the mylar tinsel forward in evenly spaced open turns so red shows between the wraps, catch it off, fold it back and take a couple more wraps to really lock it in.
Tie in a long sparse pinch of white bucktail underneath as the throat, reaching back to about the hook point and beyond, and snip the butts.
Prepare the wing ahead of time: stack four purple feathers and put a drop of UV resin where the barbs meet the stems, cured hard, so all four tie in as one unit. Lay them on top with a couple of loose wraps and check the angle before locking in; if they lie too close to the shank, add a thread bump behind them and tie them in ahead of it. Snip the butts.
Tie a jungle cock nail on each side as a cheek, two wraps at a time so you can reposition the angle, then secure both and snip the excess.
Tie in four strands of peacock herl on top as a topping, as long as the feather wing, with a couple of loose wraps at the catch-in point and tighter wraps forward of them; trim the butts.
Build a big streamer head, taking the thread right back to the eye and ramping it up again, then whip finish and coat it with UV resin.
Slide a bodkin under the peacock herl, pinch it down with your thumb and pull back with a little pressure to put a curl in the strands; repeat if it does not take the first time.
