Double the end of the leader belly forming a loop about 6 inches long.
Form a smaller loop about 2-inches from the end of the leader belly
so that the smaller loop is behind the doubled line.
With the larger loop, make a wrap around the smaller loop and pass
the end of the larger loop through the smaller one.
Wet the knot area and firmly pull the larger loop. Be sure the wraps
tighten evenly. Trim excess.
To connect the perfection loops, pass the tippet loop over the leader
belly loop, then pass the fly through the leader belly loop.
