Step 1: Materials and Tools
@ Sticky tape,
@ Light string,
@ Long straight edge.
Step 2: Making the sail
Mark points approximately half-way along the top and bottom edges, and about one thrird of the way down the side.
Join the points. (The dotted line is not essential - it is just to show where the longerons are going to be later.)
Cut along the lines and discard the triangular pieces.
Step 3: Longerons
Take another double page of your newspaper. Roll it up tight from one vertical edge and tape together.
Make another roll of paper.
Decide which side of your sail will be facing you in flight, and place that side up. Tape one longeron on each side of the sail, where the dotted lines were in the previous step.
Notice that the end of the pice of tape folds over the edge of the sail and is stuck behind - a simple trick, but it makes the kite a lot stronger.
Step 4: The Bridle
Turn the kite longerons-down, and attach the string from corner to corner, using tape at each corner.
Tie the ends of the bridle together to make a loop. A reef knot (I think US readers may call it a square knot) is fine for this. The bulk of the loop should be in front of the kite.
Note that I have attached the string waaaay off-centre. This prevents the knot from obstructing the flying line when we attach it later.
Step 5: The Tail
Cut along the creases to make eight strips of paper, about two inches wide.
Tape four strips together, end-to-end. That's one tail.
Tape the other four together. That's a second tail.
Tape one tail to each lower corner of the sail.
Your kite is basically complete.
