Step by Step.
Double the last few centimeters
of the heavier leader and thread
the lighter line through, then around,
the resulting loop.
Continue wrapping down the loop in the leader
with the lighter line.
Make five wraps down the loop
then commence wrapping in the other direction,
back over the first wraps.
Complete five wraps in each direction
and thread the tag back through the loop
alongside the main line.
Partially close the knot first with gentle pressure
on the main line and tag of both leader and line.
When the knot begins to tighten, let both
the tag of the line, and tag of the leader, go.
Then tighten the knot with firm pressure
on line against leader.
Close the knot and trim the tags.
