Fly Goddess:
"My only question is, I tie a Damsel Nymph out of Ostrich along with the four feather nymph, but is I use it all day, the color fades quite badly. What were once beautiful Olive Ostrich flies are now an off white or pale light green." ~Fly Goddess
You fly fished all day, and catching all those fish, and you are worrried about the color fading on the nymph? Let it dry out, and then use a Sharpie Pen and color the faded coloration for the next time on the stream.
You could also make sure that the ostrich herl color has been fixed by soaking the ostrich herl in a mixture of vinagar and water. Then it should not fade.
Some herls (especially those sold at "Micheal's and "JoAnn Fabric" have water soluable dyes, that wll leech out if the herl gets wet.
As for people catching a lot of fish with this simple nymph pattern, I apoligize. I am willing to take all the blame, although it is not my pattern. For many years, I have hesitated from sharing this fly pattern, for obvious reasons!
