Here’s a great video from Tim Flagler of Tightline Productions that shows you how to create a beautiful March brown pattern invented by New Jersey fly tier John Collins. The fly uses some odd materials—most notably brown calf-body hair and cinnamon peacock biots—for maximum imitation. I did find a source for the peacock feathers (see below), but I struck out on the calf body hair. Feel free to use white hair or tan Poly yarn.
