Method
Make a long loop at the
bight of the cord.
leaving the end long
enough to form the
successive turns. The
end must cross the
standing part (1). The
turns are made regularly
from right to left
without overlapping
each other (2. 3. 4).
You can make as many
turns as you like; the
knot will increase in size
the more turns there are.
Having done this, pass
the end through the
loop (5). This is the key
to the knot. Finally pull
the standing part to
tighten the knot (6).
