through a karabiner. In order to minimise this problem, the tails should be

seized to their respective standing parts, as otherwise they can project at
awkward angles.

Take a bight in one rope, and pass its end across beneath its standing part.
Then pass the end of the other rope through this bight and then over the
standing part and underneath the tail of the first rope (figure 20.1). Next
bring it out between the first bight and its own standing part to form a
second bight (figure 20.2), and pull the tails tight: in this way, you have
woven it alternately over and under each successive part.
