Lately I've seen many references to using materials in a dubbing loop that are not traditional packaged dubbing. I've gotten decent at spinning loops for use with simi seal dubbing and such for making nice shaggy bodies, but I'm not real sure how one would go about using other stuff in a loop. In Big E's recent SBS for the Fish Taco he mentions putting the ostrich herl in a loop rather than just lying around the hook shank. Also seen squirrel tail mentioned as used in loops, as well as krystal flash/tinsel type stuff. I've tried to wrap my mind around the concept, but I'm struggling. Anyone offer any clear insight?
