A most elementary, simple fly for the beginner. A CDC winged wet fly…the F Fly. For the beginner…leave it alone. Tie it as described. Sometimes the nemesis of the tier is to not leave well enough alone. Not sometimes, often. Partly experimentation, partly boredom, the tier takes simplicity and adds this and that. I suggest tying  some basic patterns and fishing those basic patterns to remind your self now and many times later that simplicity has its aesthetic rewards also. I notice in some of the renditions they trim the tips of the CDC to form an even wing tip. I would rather maintain the natural tips than cut them off; much like the tier is cautioned in trimming the ends of marabou to a blunt finish.
