Gordon Griffith’s 14/0 Sheer Ultrafine Thread
If you tie trout flies and have not tied with this thread, then you are missing out. This is by far my favorite thread for tying, especially small flies. The ultra sheer characteristics enable you to tie, building very little bulk, and giving you high breaking stregth to boot. The earth tone colors are perfect for matching the naturals since many of my small patterns are tied with just thread bodies.
