Nano Silk Thread 18/0

This thread is super fine, doesn't stack, and is stupid strong. Strongest thread out there for it's size. Nothing better to finish dries with, especially small ones. Once you start using this thread on flies (especially smaller ones) you'll never go back. You can also split this down the middle as you tie and then twist it making your own dubbing loop without actually making a dubbing loop. Couple things to watch out for, it doesn't knot as well as others so whip finish a few times, but don't worry about excessive build up. Second thing is it's so strong for it's size the smaller sizes will cut through foam if you pull hard.

I tried this on a recommendation and so far I'm impressed with the strength. I have been using another brand's 18/0 and only have this in black. I'll try others now though.

This is the only thread I'll use to tie dry flies now, especially for the smaller dries. Very strong thread that allows you to set your material with the least amount of wraps possible. The thread is strong enough to cut right through materials if too much tension is used.
