As the name implies, the process of creating these dubbing blends limits their production to small micro brewed batches. Small Batch Blends are a mix of natural fur blends from fox,  muskrat, hare and other animals. There are some very unique pattern specific blends produced from natural furs for flies described by earlier tyers like T.E. Pritt, Fran Betters, R.S. Austin, H.C. Cutcliffe and others.
