Figure 10-23. To split the lead of a 4L 5 3B knot, pass
the working end (arrow) in an opposite pattern to
the previous lead (shaded), going over where it goes
under and vice versa. Continue following opposite
to the previous lead until the end once again meets
up with the standing part (C). You’ll have a series of
“bars”—sections going under two or over two—facing
you. Restore symmetry by passing the end under the
bars that go under two and over the bars that go over
two (C and D). By doing so you’re also continuing to
travel opposite the previous lead. Double and triple to
get the finished knot (E).
