EP Wooly Critter Brush 0.5 is an easy way to tie freshwater critters like Wooly Buggers and Crayfish. Its a blend of short EP Fibers and EP Sparkle combined with longer micro rubber legs. Tie it in, wrap it forward, pick it out and tie it off. Its that simple to get a super buggy look to your next pattern. Using it on Crab and Shrimp flies will produce bites as well.
