TIEMCO Semperfli Spyder Thread Yellow – Ultra-Thin Translucent Micro Fly Thread, 100m

Overview of TIEMCO Semperfli Spyder Thread Yellow

Designed for micro fly tying, Spyder Thread Yellow is an ultra-thin, two-ply polyester thread that brings finesse to delicate wraps. Its light twisting and non-waxed construction help the thread lay flat as you wind, reducing bulk and allowing precise control on the smallest patterns. At about 400 g break strength and an 18/0 (30D) sizing, this thread blends strength with a feather-light feel, making it a versatile choice for both dries and wets.

The thread is translucent, a deliberate feature that lets the fly’s hue show through. On tiny patterns, this translucency can subtly influence the overall tone without overpowering the pattern, helping you preserve natural color cues while adding a touch of polish. The result is a clean, refined appearance that can enhance the realism of your smallest flies, such as midges and emergers.

Spool density and handling are practical advantages you’ll notice in the work queue. The spool holds 100 meters of thread, giving you ample length for multiple builds. A non-waxed, lightly twisted core keeps the thread tidy on the bobbin, and the ability to split the thread into two 50:50 strands offers even more control for ultra-fine wraps. The fibers lay flat when wound, reducing the chance of snag or snag-related miswraps during complex patterns.
