Moonlit NYLON Fly Tying Thread (200 Yard Spool)

Tie with control, confidence, and exceptional value. Moonlit Nylon Fly Tying Thread is a smooth, high-performance tying thread designed for everything from delicate dry flies and small nymphs to streamers, foam flies, and larger patterns.

Its unwaxed nylon construction allows the thread to lie smooth and flat for clean, low-bulk bodies and precise material placement. Add twist when you want a tighter, more concentrated thread or flatten it when you need broader pressure and a smoother underbody. It can also be split for split-thread dubbing techniques, giving tiers greater versatility at the vise.

Each spool contains a generous 200 yards of thread—providing significantly more tying material and lasting value for both recreational and production fly tiers.

• Generous 200-yard spools
• High-performance fly tying thread at a premium value

Choose the Right Thread Size

70 Denier

Our finest option for small flies and low-bulk tying. The 70D thread is ideal for dry flies, small nymphs, midges, and other patterns where precise material placement and a slim profile are important.

Best for: Small dry flies, midges, nymphs, soft hackles, and low-bulk patterns.

105 Denier

A versatile, all-purpose fly tying thread that balances a refined profile with dependable tying strength. The 105D is an excellent everyday choice for trout flies and a broad range of common patterns.

Best for: Dry flies, nymphs, wet flies, smaller streamers, and general-purpose fly tying.

140 Denier

A heavier thread for larger flies, bulkier materials, and applications requiring greater holding power. The 140D provides the control needed for securing hair, foam, zonker strips, and other substantial materials.

Best for: Streamers, foam flies, bass flies, larger nymphs, hair-wing patterns, and heavy-material tie-ins.

Smooth Control with Less Bulk

Thread buildup can quickly change the proportions of a fly. Moonlit Nylon Fly Tying Thread can be flattened as you wrap, spreading the tying pressure across a wider area and helping you create smooth underbodies, clean heads, and more consistent finished flies.

When additional bite or more concentrated pressure is needed, simply add clockwise twist to tighten the thread. This ability to control the thread’s profile makes it adaptable to different materials, techniques, and stages of the tying process.

Made for Split-Thread Techniques

The unwaxed nylon fibers can be carefully separated for split-thread dubbing. This allows dubbing, fur, and other materials to be placed directly between the thread fibers and spun into a durable, naturally textured body or collar—without creating the extra bulk of a traditional dubbing loop.

What to Expect from Unwaxed Nylon Thread

Because this is an unwaxed nylon thread, it offers a smooth feel and excellent control over how the thread lays on the hook. Compared with heavily waxed thread, materials may require deliberate thread tension and secure initial wraps during placement. This gives experienced tiers greater control while still remaining approachable for everyday fly tying.

Nylon also has a small amount of natural elasticity. That slight stretch helps maintain steady pressure on materials, but—as with any tying thread—the best results come from smooth, controlled tension rather than sudden pulling.

More Thread on Every Spool

With 200 yards per spool, Moonlit Nylon Fly Tying Thread gives you more time at the vise and fewer spool changes. Whether you tie a few flies for your next trip or produce patterns in larger quantities, it delivers the performance, versatility, and value serious fly tiers expect.

Choose the denier that fits your flies—or keep all three at your bench so you are prepared for everything from the smallest dry flies to durable foam and streamer patterns.
