I have attempted this technique quite a few times with poor success, but recently I came across this website http://www.flyanglersonline.com/flytying/advanced/part1.htm. It makes the process very understandable. I will submit a couple of woven body flies to the Fly Library in the next few days. One more benefit of the snow.
Sorry Harley, I see the url doesn't go anywhere. Try this: go to http://www.flyanglersonline.com/ On the left side of the page click Fly Tying. Then, on the left click on advanced tying. Now start with the Bitch Creek Nymph and work your way through the recipes. Nostrildamus, look on the tool bar just below the flyfishbc logo.
