How to tie it
Cut a foam strip one hook-gap wide and taper the rear end; with a marker, pre-mark 3 evenly spaced segment lines so the finished back looks jointed.
Lay a thread base and bind the foam strip on top of the shank at the bend, tip extending a short stub past the bend as the tail.
Dub a thin underbody of tan-gold (or orange) dubbing forward to the 70% point.
Pull the foam forward over the back and lock it down at each pre-marked line with 3-4 tight thread turns, building 3 segments. Do not overcompress; the foam is the float.
At the front segment, tie in round rubber legs with figure-8 wraps, two per side, angled back.
Tie a sparse EP-fiber wing flat over the back, reaching just past the bend.
Fold the remaining foam back to form a bullet head, add a small orange poly indicator tuft on top for visibility, whip finish under the head, and trim.
