The Prusik knot. Where would kite-fliers be without this great shiftable, lockable knot... A bit of a pain to tie at first, but it makes adjusting a bridle so easy! Pulling the bridle straight unlocks the knot, letting you shift it along the bridle line. Pulling on the lines as pairs as in the last photo causes the knot to fold, locking it in place.
I use the Prusik on horizontal bridle loops to shift the knot left or right across the kite, for trimming purposes. More commonly, it's also used to slide up and down the bridle line of, say, a Diamond kite to adjust the Towing Point fore and aft.
On kites with 4 legged bridles, arranged as an upper and lower loop plus a connecting line, this means 3 shiftable knots. For example, the Dowel Rokkaku and Dopero. At least you only have to tie these knots once.
Although it seemed a little excessive at the time, I took this approach on even my smallest Dopero. A tiny kite with a 30cm (12") wingspan. But it sure paid off, since some fiddling was required to get a decent flight out of it!
More recently, I have also used this knot on the vertical bridle loops of a large Genki. Same deal, tiny adjustments can trim the kite left or right.Now, if you really want to go overboard with knot-tying...
There are other ways, some possibly a little simpler, to obtain a shiftable knot. However, the Prusik has worked so well for me over the years that it's the one I would recommend.
This mountaineering knot was invented in 1931 by Dr. Karl Prusik. With one 's'. At least this web-master has finally got it right. Many others still haven't! Prusik later authored a mountaineering manual, which was the first publication to feature this well-known sliding knot.
Tying a Prusik knot actually becomes fun after a while, funnily
enough! Be sure to put a Simple knot into the short end of the line
though, since constant use tends to pull line through the knot. The
short end gets noticeably shorter than you remember tying it originally.
Perhaps this happens during locking and unlocking...

This was an experiment with mounting a camera directly onto the kite. With winds gusting to over 30kph up high, the Fresh Wind Barn Door kite was selected...
In a word, it was tricky. I mounted the camera as close as possible to the center of gravity of the kite, but it still ended up quite a few cm closer to the trailing edge than I would have liked. It was only practical to mount he camera - on its bendy tripod (!) - near the diagonal spars crossing point. Electrical tape secured 2 short tripod legs to the diagonal spars, holding the camera upright with the kite sitting on its trailing edge.
It was a struggle to get enough lift to gain much height, and the kite swung dangerously from side to side. Might try the drogues next time! I did my best to urge the kite higher in mid-swing.
Eventually, for a few seconds, the kite got to around 100 feet on almost 200 feet of 200 pound Dacron.
A video clip will of course be forthcoming on Facebook. And only seasoned kite fliers will bother watching it all the whole way through, possibly wrestling with sea-sickness all the while. Hence the title of this post. Still, it was an interesting, if slightly nerve-wracking, outing! At shoulder level, the breeze measured around 9kph gusting to 18.5kph. Some low cloud over the hills was absolutely tearing along, perhaps up around 40kph.

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.
Very satisfying making your own and watching them get air-born for the first time."
"I've just bought your super e-book and spent most of last night pouring through all the great stuff in it!
Very detailed and USEFUL information - thanks for such a great book."
years ago, I tried making a kite using the 'instructions' in a free
kite-safety booklet. What a disappointment for a young boy.
Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"
"omg i made a kite from this site and i fly it ....... booom i didnt expect this bc in the other sites instuction are trash
to try these books
