Lay out you sail material on a nice clean flat surface and measure as accurately as you can, the dimensions as shown on the plan above, cut off the 4 outside triangles leaving the kite shape, cut carefully, no jagged edges, if you use polyethylene or mylar before you cut put a line of sticky tape right over the line, this will strengthen the edges thus reducing the risk of a tear. You should now have before you a limp kite shape. Put a couple of layers of sticky tape on the back side of the points marked as the bridle points, this will add strength for when the bridles are attached. Make a small hole through each bridle point, it is best to punch or cut the hole rather than poking something through, reducing the risk of tear.
First stick down the spine with one long piece of tape then cut the single cross spar to the width of the kite, do not stick it down yet. At the ends of this cross spar, make two notches, this will enable you to attach a bowstring, attach a length of string to one end then pass the line through the notch, pull the string tight and make the spar bend slightly. Run the string to other notch and make a nice knot in the line, so that it jams in the knot, this bow should be of 4 inches or 10cm at it’s maximum point ( in the center) unhitch the knot and stick the cross spar to the kite securely. When you replace the string the whole kite will bow.
The bridles are the lines which connect the kite to the flying line, pass a length of line approximately 1.2m or 4 foot through the holes you made earlier so that you have a single piece of line on the front of the kite tie this off at both ends to the spine at the back of the kite.
With the kite facing up lying on the floor, pick the kite up with the string, find the point on the bridles that makes the front end, lift first and reach a height of around 10cm from the floor, before the rear (bottom, tail end) of the kite starts to lift off the floor, this point on the line will be your towing point at which, you will need to make a small loop and attach the flying line.
Tails ( optional )
If you have made the kite evenly and accurately you should not need tails, some people like tails however, so to make them cut long thin strips of at least 1.5 meters of sail material, about 3 pieces looks nice, stick these with tape or tie them with line onto the bottom end of the kite
This kite should not need much wind to fly, do not go out on a very windy day, a light breeze is all you need, STRONG WINDS BREAK KITES, Do not run madly with the kite, it should fly out of your hand, be careful not to fly near any overhead power lines, or any other dangers such as roads, railway lines, airports or cliffs ! and be considerate of others when flying your kite and obey local laws regarding height, as a guide keep your kite below 200 feet / 60 meters.
