A flying line to keep the kite from blowing away.
Kites can be large or small and of an unlimited variety of shapes.
Early kites were wooden frames covered leaves, silk and paper while many modern kites are made of space-age plastics or synthetic fabrics. Although kite classification is not rigidly defined, you may try to identify kites by these categories. Although there are many variations among flat kites, most need tails for balance and stability. Bowed kites may be similar in appearance to flat kites except for the dihedral angle formed by bending one or more of the frame sticks. Most bowed kites do not need tails because the bowed curve functions like the wings of a soaring bird to maintain balance.
