Turle Knot - Improved Turle Knot The Turle Knot is a popular knot for connecting a fly with a turned up or turned down eye to a line. There are several variations to this knot and this one would be considered the "Improved Turle Knot". Left Kreh suggests tucking the tag end through the large loop before tightening the knot onto the hook eye, but that is optional.

1. Thread fly onto tippet and leave several inches of tag end to form the knot. Double the line back onto itself toward the fly and then bring the tag end behind then over the doubled line, making a loop. Pass tag end twice through the loop created, essentially tying a double overhand knot.

2. Tighten down the knot just created and slip the loop over the fly. Pull on the leader to set the knot tight against the hook eye.

3. Trim the tag end.
