Double Slip Knot
The Simple Slip Knot is, in effect, a
Single Bow Knot; the ''bow" being
the loop or bight. You can tie a
Double Slip Knot or Double Bow in
the center of a long rope by forming
an overhand loop (as shown in fig. 1)
and drawing a bight up through it
with the right hand, while the left
presses a bight down through it (fig.
2). Pull both loops through, thus
tightening the knot between them and
the Double Bow results (fig. 3). By
drawing on the single portions of the
rope, the knot is quickly undone.
