STEP 2 Tie a Half Hitch (see previous) around the standing part.
STEP 3 Next, tie a second Half Hitch.
The Round Turn and Two Half Hitches is the most common hitch used
for tying off a rope when you know you won’t need to adjust it after
tying. The most important feature of this knot is the round turn. If the
rope you are tying is already under strain, the extra turn will help hold
against it while making the Half Hitches and will continue to reduce the
strain on the Half Hitches.
