Use to tie a loop in end of leader. The perfection loop is the easiest way to tie a tiny loop or one that is perfectly in line with the standing part of the leader.
Form a single loop by bringing the tag end behind the standing part of leader. The tag should be on the right-hand side.
Form a second, smaller loop in front of the first by bringing the tag end in front of and then behind the first loop. End with the tag on the right again. Keep the loops in place with thumb and forefinger.
Pass the tag end between the loops and hold in place.
Pull the second loop through the first loop with right hand. Make sure tag end does not slip out of position. Lubricate and tighten by pulling on second loop and standing part of leader. The knot works best when loop is kept small.
Trim tag end as close to knot as possible.
