Step 6 Lay the line tightly across the kite back, side corner to side corner, with the knot in the middle. Secure with three pieces of sticky tape at each point.
Step 7 Fold the sail (straws on the inside) and match up the two side corners so they are exactly together.
Step 8 Now take the two lines together in your forefinger and thumb and run them out to the loop at the end. Tie a knot that leaves 1 to 2 cm of thread loose.
Step 9 Hold the loop and check the two sail edges are matching. If they don't, undo the loop and repeat this instruction.
NOTE: The sail edges must match. If they don't, the kite won't fly very well!
