This new material was designed specifically for tying the super popular fish catching GAME CHANGER flies by Blain. The material is stitched on both ends so you render more flies per pack. You can trim at an angle to achieve a taper as you wind. The left over trimmed piece is useable for another segment or fly. GAME CHANGERS have never been so easy to make! No more gaps between the segments. Best of all the design of the material allows for the body of the fly to be tied thicker. In turn making the fly swim better in the water.
