TIEMCO Semperfli Spyder Thread Steel – Ultra-Thin Micro Fly Tying Thread

TIEMCO Semperfli Spyder Thread Steel: Ultra-Thin, Translucent Micro Fly Thread

Experience a thread that feels almost silky in the hand yet performs with surprising strength. Semperfli Spyder Thread Steel is engineered for delicate fly tying where control and presentation matter. Each 100m spool offers long use in the workshop or on the water, reducing stops to change spools during a session.

Built as an ultra thin polyester micro thread, it is 2 ply and easy to split into two 50:50 strands. The weave is lightly twisted and non-waxed, so wraps lie cleanly and sit flush against the hook shank, helping to maintain a natural silhouette on tiny patterns.

The translucence of the thread is a deliberate feature. Because it blends with the fly hue rather than overpowering it, this material helps preserve the character of small patterns such as midges where color is part of the illusion rather than the spectacle.

Key benefits at a glance

• Perfect thread for micro fly tying
• 18/0
• Use with any type of bobbin
• Lays flat
• Stronger than Uni Caenis and Danville Spiderweb

Anglers who chase small bugs will notice how the thread behaves at the vise. It wraps with a light touch, holds tight where needed, and splits into two strands when you want lighter ties or double wraps with less bulk. The midge pattern in particular benefits from a fine, translucent underlayer that remains unobtrusive as you build delicate heads and thoraxes.

Practical use tips show the versatility on both dry and wet styles. For midge or small mayfly patterns, the color remains a whisper rather than a shout, making it a prudent choice for patterns where finesse matters more than visibility. The 100 m length keeps your workstation productive, and the material is strong enough to handle small tippet and nuanced wraps without fraying or creeping.
