Spyder Thread 18/0 is a fine 30D, 18/0 traditional tying thread, and is specially developed to be semi translucent so that the threads help adopt the shade of the fly pattern. Spyder Thread 18/0 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 Spyder Thread 18/0 in comparison will give the fly tyer confidence when tying small flies that their thread will hold better. With 2 strands Spyder Thread 18/0 will also lay reasonably flat when tying flies. Spyder is aimed for fly tyers wanting to tie small flies as an alternative to threads like Uni Caenis or Wisp which are weaker threads. Spyder Thread 18/0 is an unwaxed thread. We do make a waxed version also off our 18/0 Spyder thread which is designed to give more grip from the wax on your materials as you tie.
There are 100m / 109 yards (approx ) per spool of Spyder Thread 18/0
