Hitches
The half hitch is the start of a number of other hitches
and is useful all by itself as a temporary attaching knot. It will hold
against a steady pull on the standing part, especially if a stopper knot
like the stevedore's knot or figure eight is put in the end.
This is a reliable and useful knot for attaching
a rope to a pole or boat mooring. As its name suggests, it is two half
hitches, one after the other. To finish, push them together and snug them
by pulling on the standing part.

These hitches are more complicated versions of the above.
