Tie your kite string and handle to the center of this line, knotting several times to secure. Tie a tail approximately 5' to the end of your kite. You can use flag tape or old scrap fabric. You may need to adjust the length of the tail depending on the amount of wind. Permanent markers may stick best to the plastic when you're decorating it.
