Dubbing:
Refers to a fur material, or mixture, or blend of furs, suitable to making fur bodies for flies. Also the process of twisting fur on to a waxed thread in order to make a workable substance for application as a fur body. Sometimes refers to the process of picking out hairs or fibers from fur bodies with a dubbing needle to form psuedo legs or to enlarge thorax areas of fly bodies. Other materials such as Kapok are also used as dubbing material.
A dubbing loop consists of a loop of tying thread in which the dubbing material is placed and then twisted to trap the material and is then wound onto the hook shank to form the body.
