Egg Veil is a very soft, yarn-like fiber typically applied to egg patterns. Place a small amount of Egg Veil around the head of your egg flies so that it "veils" over the egg portion. Egg Veil makes them more realistic and adds a touch of movement to the fly. Many angler believe Egg Veil can be important for picky fish that have seen every egg pattern out there. Excellent for fooling finicky rainbows in Alaska.
