I have a Marc Petitjean whip finish tool; when I'm done tying a fly and do my whip finish thing, regular thread doesn't break. However, when I use Pearsall silk and release the silk from the bottom hook, while tightening the silk, it ALWAYS breaks! I have noticed that the silk is made up of 3 individual threads... I assume somehow they get caught up on each other and snap... (just a noob's guess).
Any suggestions on how to whip finish using silk successfully?
