2 Make Your Own Kite Materials: Butcher cord or thin garden twine Scotch tape or glue 1 sheet of strong paper (102cm x 102cm) 2 strong, straight wooden sticks of bamboo or wooden doweling 90cm and 102cm Markers, paint or crayons to decorate your kite. *Check with an adult before you begin. 1. Make a cross with the two sticks, with the shorter stick placed horizontally across the longer stick. Make sure that both sides of the crosspiece are equal in width. 2. Tie the two sticks together with the string. Make sure they are at right angles to each other. To make it even stronger, dab some glue to stick it in place. 3. Cut a notch at each end of both sticks. Make it deep enough for the string to fit into. - Cut a piece of string long enough to stretch all around the kite frame. - Make a loop in the top notch and fasten it by wrapping the string around the stick. A kite consists of these basic parts: Spine: The up-and-down, or vertical stick that you build your kite around. Spar: The support stick(s), that are placed crossways or at a slant over the spine. Sometimes they are curved or bowed. Frame: The joined spine and spars, usually with a string connecting their ends, that form the shape of the kite and make a support for the cover. Cover: The paper, plastic, or cloth, that cover the frame to make a kite. Bridle: One or more strings attached to the spine or spars, which help control the kite in the air. Flying Line: The string running from the kitesʼ bridle, where you hold to fly the kite. Tail: A long strip of paper or plastic of ribbon that helps to balance the kite in flight. Not all kites need tails. Reel: The object you use to wind your flying line, to keep it form getting tangled or flying away. - Stretch the string through the notch at one end of the crosspiece, and make another loop at the bottom. Stretch the string through the notch at one end of the loop at the bottom. - Stretch the string through the notch at the other end of the crosspiece. - Finish by wrapping the string a few times around the top of the stick and cutting off what you donʼt need. This string frame must be taut, but not so tight as to warp the sticks. 4. Lay the paper flat and place the stick frame face down on top. - Cut around it, leaving about 2-3cm for a margin. - Fold these edges over the string frame and tape or glue it down so that the paper is tight. 5. Cut a piece of string about 122 cm long. - Tie one end to the loop at the other end of the string to the loop at the bottom. - Tie another small loop in the string just above the intersection of the two crosspieces. This will be the kiteʼs bridle, the string to which the flying line is attached. 6. Make a tail by tying a small ribbon roughly every 10cm along the length of string. - Attach the tail to the loop at the bottom of the kite. 7. Decorate! Source:
