I hate tying sparkle duns, mainly because I can't; this variation makes it almost fun. Tied here as an Adams/callibaetis; change color/size to suit your needs.

hook - WFC Model 3 #14
thread - UTC 140 grey brown
shuck - Congo Hair brown
abdomen - tying thread
loop - tying thread
hackle - grizzly
thorax - dubbing hare's ear (too lazy to dig out the muskrat)
wing - deer hair

Part 1

start thread one eye width back from eye

clean, stack, measure (hook length) a clump of deer hair; spin the thread tight and tie in

pull some fibers back, take a wrap thru, repeat, set wing angle with wraps in front and trim butts

tie in CH at base of butts, fold over, wrap to bend; return to base of wing, creating tapered body, trim shuck (gap width)

create loop

tie in hackle; insert loop onto gallows

wrap hackle up (distance = back of thorax to eye)
