Multifold overhand knot

A cluster of these knots can sometimes be seen adorning the waist ties of nuns and monks, as a

reminder that the wearer is bound to his or her vows of poverty, chastity (or celibacy), and
obedience. Barrel-shaped knots of this sort also form the basis of other strong and secure knots,
although, depending on the material in which they are tied, they may prove hard to untie again.

Nevertheless, this is a useful knotting technique to master.

Tie a simple overhand knot (see page 292), then tuck the working end two, three, or more extra
times (1). Pull both ends gently in opposite directions, allowing the knot to twist and wrap around
itself (2). Work it snug and tight (3).
