I think you can learn a lot of precise sewing techniques just from making this kite, see the very detailed Plan.
Also check out an interview with designer.
The flight card is in German, but gives you a good idea of the sort of flying style.
And a video of a different kite by the same guy, but it's supposed fly like this:
