Semperfli Spyder thread has been a long loved thread for tiny flies. Now we have taken it to the next level with 18/0 Classic Waxed. 18/0 Classic Waxed, a traditional tying thread, was specially developed to be semi translucent so that the threads help adopt the shade of the fly pattern. 18/0 Classic Waxed has 2 fine strands of thread twisted together. It has a breaking strain of approximately 400gm - for comparison tests show Uni Caenis to have a breaking strain of 85g & Danville Spiderweb breaking strain is approximately 142gm. The strength of 18/0 Classic Waxed in comparison will give the fly tyer confidence when tying small flies that their thread will hold better. With 2 strands 18/0 Classic Waxed will also lay reasonably flat when tying flies. 18/0 Classic Waxed is aimed for fly tyers wanting to tie small flies as an alternative to threads like Uni Caenis or Whisp which are weaker threads. In developing 18/0 Classic Waxed the team wanted a micro thread which had some strength, laid flat
