CROWN SENNIT

The Crown Sennit is based on a series of Crown Knots (see Chapter 1),

but with four strands instead of three. To begin, bind four cords or ropes
together, with tape or a Constrictor Knot (see Chapter 6) tied in string.

STEP 1 Form the first Crown Knot, as shown.

STEP 2 Tighten the first knot, and make another one.

STEP 3 Tighten the second knot on top of the first one and continue
tying Crown Knots, one on top of the other.
