Double Bow

This may be tied in either of two
ways. The first and preferable method
is to start exactly as with the Single
Bow Knot, allowing a fair amount of
length to the working end. Tie the
first Overhand Knot.
In tying the second Overhand,
form a bight in "B," but instead of
pushing end "A" through the new
loop, draw a bight through, so that
"A" becomes identical with "B" in
formation. When it is drawn tight,
you have two loops instead of one. A
pull on either end ("A" or "B") will
undo the knot.
The alternate method is tie a Single
Overhand, then form identical bights
in "A" and "B." The bights
themselves are then tied in an
Overhand Knot on top of the first
one. It results in the same formation,
but is a little slower.
The Double Bow is the familiar
Shoestring or Shoelace Knot.
Everyone is familiar with it, but it can
be tied in either the "right" way or
the "wrong" way. The right way is to
follow the pattern of the Square
Knot. It will go wrong if the ends are
reversed in tying, as with the Granny
Knot.
