A lot of newbie fly tyers will look at the thread last, thinking it doesn’t matter. However, next to the hook, your thread is one of the most important components of your fly tying kit.

I can’t count the number of times I’ve had to retire a fly due to the thread unraveling from the fly. I would say it’s second only to snags in terms of reasons why I can’t use a fly anymore. 

Here are some of the best fly tying threads that I have used over the years:
