HALF HITCH

There are two basic ways of making a Half Hitch. It can be tied off with
a running end, or it can be tied off with a bight, which makes it a
Slipped Half Hitch.

STEP 1 Bring the running end around the ring and then around its
standing part. Then, tuck the end inside the crossing turn, next to the
ring.

STEP 2 Another option is to make a last tuck with a bight, making it a
Slipped Half Hitch.
