STOPPER KNOT

Quick and easy to make,
this stopper knot can also
be quite bulky, so it is
particularly suited to its
purpose.
Method
Using a piece of line of the
largest possible diameter,
make a loop around the
main line (1). Then make a
long series of turns to
increase both the size of
the knot and its grip (2),
but check while doing so
that they do not overlap or
come out of order.
Although overlapping
turns would certainly
enlarge the size of the
knot, the advantage would
be dubious for it would
soon begin to slip. Close
the knot by inserting the
end into the eye of the
loop and tighten it by
pulling on the end and the
standing part at the same
time (3).
