Shane Stalcup (RIP) came up with a great way to get the most out of lower-quality CDC feathers. Tied here in PMD colors; change to suit your needs.
hook - Dai Riki 125 #16
thread - UTC 70 yellow
shuck - Congo Hair brown
body - biot PMD
hackle - pale yellow CDC fibers
post - Congo Hair white
thorax - Superfine dubbing PMD
Part 1
Mash down barb, attach thread at point above point
tie in shuck and wrap back halfway down bend
tie in moistened biot; wrap to initial tie-in
Cull through your CDC shorts, broken-tipped and otherwise lesser loved CDC feathers and strip off some fibers; tie in
tie in hank of CH directly on top of CDC; figure-8
