Fly tying would be utterly incomplete without mentioning the significance of flash material. Flash material is the shiny material that often lines a fly. You’ll often see stringy, shiny material lining the tail of a custom fly - this is where you’ll find the flash material. While it may all look just about the same, there’s actually a great variety between different kinds of flash material. Certain materials are thicker or thinner, are different colors, or just have different levels of flexibility and flow. As you grow into the craft of flyfishing, you’ll begin to learn what you need in a fly given the circumstances. Flash material will also begin to make more sense once you do your research! If you’re a somewhat experienced angler, you know that research plays a huge role in working towards the ideal setup, and especially when it comes to fly tying flash material. In time, anyone can begin to see the differences. In any case, keep tabs on our listings for special flash material that you may not find anywhere else!
