This "one feather fly" is a very simple and highly underestimated fly. You can even tie it without the hackle and just bring some wing points down with your thread to imitate the legs. Indelible markers can help you to darken the body, tails and/or legs to your liking or to match the hatch. Tie it in three different colours and sizes and put the necessary markers in your fly fishing vest. You get a low sitting but very light dry fly with remarkable catching properties. Very nice, Scoobyscott.
