Hair, I like to make my flies look good. For the colored head I use two colored markers, pink and olive. I first coat the head in Sally Hansens "Hard as nails" onto my white Danville Falt Waxed Nylon thread. After the nail polish dries, I color the head. I reapply another coat of hard as nails after the marked color dires.

I think it adds a great finishing touch.
