Flashabou is an essential material for the steelhead tyer. It's been made popular in patterns like the Prom Dress from Scott Howell and Cold Medicine from Ken Morrish where it's the dominate material in the fly. It can also be used subtly in patterns to give them some extra presence in the water. We also use it for bodies on intruders and as flashback material for nymph. Whatever your purpose, Flashabou is a must have.
