I have used it for San Juan Worms, Red wigglers and other worm patterns. I usually use 20-30 lb. test for them. I have tried to use it for tying on bucktail but it would eventually work loose and never held tight. I think using a really good head cement would help a lot. I have taken 50 and 75 lb. test and melted the ends for eyes or tied knots in it for legs. As a body material it works really well and anything and everything you put under it shows through really well even with the red and yellow colored lines. I would bet you could make some wicked river witches with it and hellgramites.
