Answer:
Apparently, farmers also used kites as flying scarecrows to frighten off birds in the fields. Wau are also flown for the sound they make which lulls the children to sleep, leaving the adults more time for work. Some kite makers leave a wau flying at night and fall asleep to the sounds of the kite.
In a somewhat unique process, designs are traced onto paper or tissue before being carefully cut out. The piece with the hole in it is then pasted onto the kite! After many such pieces of different colors are applied, intricate patterns emerge. Shiny foil paper is commonly used, to get the vibrant and complex effect.
