We were asked to design a fly tying knots bandanna for Project Healing Waters Flyfishing and here it is. We carry a few bandannas in stock at a time to help raise funds for this terrific organization. It's a good example of our partnering style as a designer and product purveyor for conservation and education non-profits. If your chapter or business might want a custom designed product, just as a bandanna, give us a call. In the meantime, here's one terrific and useful bandanna for your fishing efforts. Blue ink on natural toned cotton. Call for hand-dyed availability. Standard size: 22 inches square. 100% Cotton.
