Below is a video tutorial how to tie a larks head knot or loop.
This is the only knot you ever need for flying sport and stunt kites.

Use the larks head knot to attach flying lines to the bridle points (pig tails) of your stunt kite.

At the other end of the lines use this knot as well to connect flying lines to your hand straps.

Make sure the coloured loops (e.g. red & green) on flying line ends correspond to your right and left hand and to the right and left side of you stunt kite bridle.
