Hareline Dubbin Cactus Chenille is reminiscent of Christmas tinsel garland but in a miniature form and a lot more color choices. It is made to be wrapped around the hook shank to form spiky shiny bodies or heads on flies. It is a quality material, coming in many great colors, with enough in each package for many flies.
It's like Ice Chenille with pearlescent fibers which makes it sparkle. Also similar to Polar chenille, but with shoeter fibers meaning it undulates less underwater and adds durability.
