Hends Peacock Hair is an iridescent fiber that moves freely in water. The manufacturer states that it does not absorb water, which makes it possible to tie a streamer using a significant amount of this material.
The material can be used to make all or part of a streamer, or to complement a natural base with a few fibers. It is also used for tags on nymphs and wet flies. A small amount adds a shimmering accent; a thicker tuft helps define the wing’s silhouette.
