I am trying to work out the recipe for a white intruder and cannot figure out the webby, mottled material used along with the ostrich plumes on the collar. At first it looked like guinea feathers, but these are much longer and webbier. I have also considered lady Amherst, but that is quite it either. Anyone have an idea what this material is? I have seen it on a number of intruder patterns in many colors, like royal blue mixed with purple ostrich, etc. Hope someone can clue me in. Thanks in advance. BTW, I'm not talking about the long slender grizzly hackles either, figured that much out already.
