First, if it's very windy outside, stay home! This is a light-to-moderate-wind kite and won't like being launched in a gale.
Barn-door kite stories of my real-life flying experiences are worth checking out!
Illustrated with photos and videos, of course.
Assuming there is some breeze outside, just dangle the kite at arm's length until the wind catches it. As long as you feel the kite pulling, let out line slowly by taking loop after loop off the winder.
Another approach is to
get a helper to hold the kite up and let it go, on the end of maybe 10
or 20 meters (around 50 feet) of line. This way, the kite soon gets high
enough to make it easy to let more line out.
Have fun flying, and I hope you've enjoyed learning how to build a barn door kite!
As mentioned earlier, there's more kite making on this site than you can poke a stick at :-)
