The original flash material! Works great on any streamer, pike fly, or nearly any other patterns. Works well for wingcases on nymphs, such as Barr's Copper John, or as an underwing on hoppers. You can rib nymphs with it, or make an underbody on a bonefish pattern such as a Crazy Charlie. Flashabou is a very versatile material that should be in every tier's arsenal.
