Hemingway's Synthetic Tapered Peacock Quills Set of 6 are made from a very thin self-adhesive flexible vinyl based material. Available in 10 colors each strip is tapered from a incredibly fine 0.2mm up to 2.2mm and 100mm in length which will basically tie the body of any pattern. From the smallest patterns in the #20's and even smaller, to your largest patterns. They utilize an amazingly detailed gradient print, which gives each quill one dark edge and one light edge; you can't even get that from a natural quill. These are a great match for almost any pattern from midges, buzzers, and nymphs to your favorite dry fly pattern; these quills won't crack, break, or split leaving you with a failing fly at the worst possible time. No pre-treatment needed; our quills will change your entire view on the hassle of using quill bodies! Also available on a clear foil backing which will enable you to partially see through these quills to the underbody giving your flies that amazingly sought-after translucent 3D effect.
