Chances are you have heard of the humble Granny knot! It's a
general-purpose knot which is useful for tying two ends of a line
together. I suppose grannies from many generations have used it for
tying up a parcel with string...
As a child, the Granny is one of the first knots you learn. I can certainly remember using it with coarse twine or string.
And yet, this knot does not do a great job of fastening 2 lines together. Try it - and see how the knot tends to slip through when you apply a lot of strain.
Despite being a bad choice for fixing your flying line (!), the Granny Knot does come in handy in less demanding kiting applications.Now, if you really want to go overboard with knot-tying...
Back to the Granny...
For my kite designs, I mainly use this knot for tying a completed keel to its vertical spar. The 2 lines already have a Simple Knot tied in next to the keel's edge, so the Granny pulls the edge tightly against the vertical spar, but does not distort the keel edge.
In this situation, fixing the knots with glue is a good idea, so the keel can't shift along the vertical spar. Of course, you need to use enough glue so it contacts the spar as well as the knot itself. As a side benefit, the Granny can't come loose either.
In a keel, the flight load is shared among several lines, so a fancier stronger knot is not required. Well, I've never had one let go yet! When I say 'stronger' here I mean 'less likely to weaken the line'.
The first half of this knot is also handy for attaching
shoe-lace ties to dowel. By not completing the knot, there is less of a
bump to interfere with the other dowel when it is laid across and
secured. A drop of glue ensures that nothing shifts.

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
