"Hi! I’m Jim Dowd at Zoar Outdoor. I’m here on behalf of expertvillage.com to talk with you about fly casting and fly fishing. Now let’s go on to actual tying of knots. In order to tie a fly onto a leader, which is really very difficult to see perhaps on this video, I’ve got some larger implements that will help you to understand it. The first knot that I would like to show you is a knot to attach this make believe fly to this make believe leader. This is called a non-slip mono loop knot. To tie the non-slip mono loop, you start by making a simple overhand knot in the tippet, the end of your line. Slip the end of the line through the eye of the hook, and then back through the overhand knot so that the line through the knot and back out through the fly is parallel. Next thing you do is you make 6 simple wraps—1, 2, 3, 4, 5 and 6—and then take the end of the line, put it back through the overhand knot so again everything is parallel. The line coming out through the hook back through the loops and then the incoming bag, so it all looks like this. Then at this point I would moisten it, and the way I would do it is that I would put the entire knot in my mouth and wet it with saliva. In this case, I’m not but just assume I did. Then slowly, smoothly pull on the end of the line and the tippet, work the knot down slowly and smoothly, and you will see that you get a knot that has a loop on it like this. Test it for strength; pull it apart, pull on this. If it breaks right now, it’s a good thing because then you haven’t broken that in a fish. If it doesn’t, you know you’ve got a good knot. This is called the non-slip mono loop because you can see that it swings freely. This allows the fly to swim naturally. It’s not pinned to the leader, which sometimes makes it look very unnatural. So the non-slip mono loop is a great knot for attaching the tippet to the fly. "
