I was on a tying forum site, and came across a material I have never herd of, nor can I find it on Google. It is used as a body baterial. It's called "NO-Dub". My question is has anyone herd of this, knows what it is. In the pic provided It looks like a slightly fiberie ultra chenille, but not as fiberie as leech yarn. or at least the extruding fibers were not as long as the leech yarn...Any info would help. If you need a visual, it can be found by looking up the SHWAPT (Swept Hackle, Wingless, All Purpose Fly) At FAOL. Thank you.
