One of my favorite tying materials, a synthetic yarn-like material called Hi-Vis, used for wings, dubbing, etc, came in a bunch of colors and was made or distributed by L & L Products of Bethpage, NY. I bought a few packets as it was being discontinued several years ago, but haven't seen it since. I'd love to find another supply, especially in black, white, rust and gray. If anyone has any they'd like to sell, or know of a source, please send me a PM.
Thanks!
