SEIZING
For the following method, it’s possible to use small string (also used for
whipping). The following diagrams show larger rope for purposes of
clarity.
STEP 1 Make a Constrictor Knot (see Chapter 6) around both ropes,
leaving one end of the string long enough to make the seizing. Make
many wraps for a distance of at least two rope diameters.
STEP 2 When the last wrap is made, tuck the string between the ropes
and proceed to make exactly two frapping turns.
