Catch the wind.....
When I was a kid, long ago in the '60s, there was no Internet and no kites-related books in my home...
Our need for something that can fly, was satisfied by applying huge fantasy, a lot of time and energy in make testing and adjustments until "the thing" was beginning to climb...
And when the kite (or almost a kite) was beginning to fly, the enthusiasm blasting around ... until the next logical decision to make a better new one!
We learnt that some are able to fly better, others aren't. And that some differences exist between flying and flapping.
The years go, profession and family taken top of the priorities.
Early or late, the desire to fly a kite come back, no matter if in the meanwhile you has been a pilot and/or an aeromodeller. No matter you have a thousand of flying hours or you made a hundred of RC models, the view of that shape of paper or fabric or film, to became smaller, high in the blue sky. To hear the sound of the line played by wind. All this is still a great sensation, a great satisfaction and a sense of happiness rise up in your heart.
A good reference kite construction book is the best bridge between the ideas and the reality and if there are children around... don't believe that to win against the modern electronic games is a too difficult duty!
Give to your child your good example, they will learn quickly. Often, they will show you to be more skilled than you believe.
