Polypropylene Macrame Yarn
This is the best stuff in the world for adding flotation to your fly. When brushed out, braided polypro creates tons of surface area in an inherently buoyant material. Perfect for yarn strike indicators as well as wings for Chubbies and Morningwood Specials. This replaces the Umpqua Stonefly Wing we previously used on the Morningwood. Try brushing a few colors together to create a mottled wing. Check out the Hareline Finger Brush for combing this stuff out...it's perfect for the job!
