Semperfli Classic Waxed Thread – 18/0 Bulk Spool
Semperfli Spyder ready waxed thread is a premium choice for fly tyers seeking durability and natural blending in small fly patterns. Developed from a traditional tying thread, Spyder features two fine strands twisted together, providing enhanced strength and a semi-translucent appearance that matches the shade of the fly pattern.
With a breaking strain of approximately 400gm, Spyder offers significantly greater strength compared to standard threads like Uni Caenis (85g) or Danville Spiderweb (142g), giving confidence when tying delicate small flies.

I’ve been using Semperfli Spyder waxed thread for several months now and it’s proven to be much stronger than the threads I used before. The two-strand twist gives it excellent strength, and the semi-translucent quality helps the fly blend naturally with the pattern. It lays flat when tying, which makes my small flies look more realistic.

This thread is a game-changer for small fly tying. The breaking strain is impressive, and I’ve never had a thread fail during a cast. The waxed finish keeps it from fraying and helps it stay in place when tied.

I appreciate the strength and the natural color match. It’s slightly more expensive than some alternatives, but the performance justifies the cost. I’ve used it on both dry flies and nymphs with good results.
