A hybrid between a thread and a fine round Tinsel, Iridescent threads are a fine tinsel wrapped around fine monofilament strands as a core. For the purpose of fly tying it acts like a fine wire when wrapped tight around a fine hook. You can also opten the strands slightly if you wish to give a slightly faceted, gleaming surface.
Originally designed for vibrant Buzzers, Chironomids, Caenis and Corixa Water Boatmen the end result is a thread that is ideal for Trout, Salmon, Saltwater, and Predator flies for bodies, thoraxes and vibrant hot spots.
