I think I remember Kelly Glissmeyer saying at one time he had used combed macrame yarn to make the indicator on his Parasol Emergers


before switching to Para Post Wing fiber, which seems to be the same or similar. For something like that application, combing out the yarn may be worth the time (although it's a bit of a pain) if you have some laying around. For tying an EP Baitfish, or similar fly, you're better off with Congo Hair or the EP fibers; better color selection, too.
