A kite line is the string or cord used to control a kite while it is flying. It connects the kite to the flyer, allowing them to maneuver the kite in the air. Kite lines can be made from various materials, including nylon, polyester, or cotton, and come in different thicknesses and lengths depending on the type of kite and flying conditions. The strength and flexibility of the kite line are important for maintaining control and stability. A well-chosen kite line can enhance the flying experience, making it easier to perform tricks or keep the kite steady in changing winds. Proper care and maintenance of the kite line can also prolong its lifespan.
