A clove hitch is a type of knot. Along with the bowline and the sheet bend, it is often considered one of the most important knots. A clove hitch is two successive half-hitches around an object. It is most effectively used as a crossing knot. It can be used as a binding knot, but is not particularly secure in that role. A clove hitch made around the rope's own standing part is known as either two half-hitches or buntline hitch, depending on whether the turns of the clove hitch progress away from or towards the hitched object.
Pick up the running end of the rope (the end that will be loose after you tie the knot). Wrap it halfway around the pole or timber.
Cross the running end over the wrapped part of the rope. This will form an "X" shape. Bring it back around the pole.
Lift the "X" part of the knot and slip the running end under this "X" horizontally.
Pull the knot tight.
