If it is the braid like Skip is talking about I love the stuff and it is easy and fast to tie. A few weeks ago I added one pack on with a order from Robert just to check it out and he sent I think 8 as free stuff. I am using it the same as chenille and have not water tested it myself, but the few local I still tie for fished it the past 10 days and I think all have come back wanting more jigs. The stuff turned the light better than anything I have ever used. Its best to heat the end of the tubing and tie it on the hook while soft and its there to stay. IT is a small body and even on old style hooks can come all of the way back to the bend for a full size jig.
