Uni 210 Denier Nylon Fly Tying Thread
Uni 210 Denier Nylon Fly Tying Thread is similar to Danville’s flat waxed nylon in that its lightly bonded fibers are easily separated for dubbing loops and lay flat on the hook. Use this strong thread for tying larger flies like streamers, poppers or deer hair patterns. This thread has a high amount of stretch compared to other options at approximately 25%, making it quite forgiving when applying extra tension.

I’ve been using this thread for streamers and poppers for several months. It holds up well under tension and lays flat on the hook, which makes it easier to tie clean and precise patterns. The stretch is noticeable but helpful when adjusting tension during tying.

Great for deer hair patterns. The thread doesn’t fray and stays strong even after repeated use. I appreciate the 100-yard spool size—it saves time when working on large flies.

Solid performance for poppers. It’s a bit stretchy, which I find useful when adjusting the hook tension. Not as flat as some waxed threads, but still effective for larger patterns.
