To get a fuller wing silhouette don't strip the fibers from the bottom of the wing feathers. After putting them together to form the wing grasp them by the rounded end that will be the tail. Stroke the fibers from the bottom up so they are outside the top fibers. Finish as usual. This method was given in TYING THE SWISHER RICHARDS FLIES BY Doug Swisher and Carl Richards. I find that I like the results better than when stripping the bottom of the wing.
