Re: Fly tying thread vs. Sewing thread. What's the difference?
Fly tying thread is cheap enough. I would use it. I like the Flymaster Plus 6/0 as a general thread. I have used a glow in the dark thread when Wal-mart sold it for some flies. But they don't sell it anymore. If you feel you must go the sewing thread route, I would use a nylon or polyester mix with nylon. I would not use cotton.
As long as I get a bite, I don't want to leave!
