Put a 3/32" copper tungsten bead on a Tiemco 2457, start the rusty brown UNI 6/0 behind the bead and dress the shank solidly back only as far as the hook point.
Tie a single strand of Red Flashabou down with three or four turns so it dangles off the back, fold the front end back, catch it with a couple of turns and trim it off.
Tuck the head end of a rusty brown pine squirrel zonker strip right up against the back of the bead, leaving a tight little neck and no wasted space, and bind it down for a fairly short tail.
Trim the tail after the fact rather than cutting the strip to length first: part the fur and cut only the leather so you are not left with a square end, then trim the flash just a touch longer than the tail.
Build a dubbing loop two or three inches long, cross the thread around to close it, and hold one leg open in the vise's material spring.
Pull a clump of fur out at a right angle to the same strip, grip it tight and pull the hide away from it; trim off any little stubs of hide left in the clump.
Set the fur into the loop, pinch just under it and spin the whirl into a furry chenille.
Wrap the collar like a soft hackle — a turn, sweep the fibers back, another turn — jammed right up to the bead but not too heavily dressed; tie it off behind the bead with a couple of tight turns and trim the loop out.
Wet your fingers, sweep everything back, take just enough thread to clean up a small head behind the bead, and whip finish with a few turns.
Add a shot of head cement behind the bead and pick everything back into shape with a dubbing brush.
