Welcome to the latest installment of our series of videos called “One-Minute Fly-Tying Tips and Techniques” from Tim Flagler of Tightline Productions. Each video will teach a single tying skill, from the most basic to the advanced. Ultimately, the series will serve as a sort of encyclopedia of tying skills that will be a valuable resource for anyone who sits down at a vise to create a fly.
Here, Tim explains what CDC (cul de canard) is and what distinguishes the two different types. (BTW, cul de canard translates as “duck butt.”) The way the fibers are arranged along the shaft of the feather sets the two apart, which is fascinating to see.
