The Granny Knot
And Its Kiting Applications
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
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...
The book Knots: The Complete Visual Guide
has an amazing average review score of 5 stars from 12 reviewers - the last time I looked. If it's a more general
knot-tying resource you need, this would definitely be it!
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.
E-book special of the month (25% off)...
e-book takes you step-by-step through making a 120cm (4 ft) tall
Parafoil kite. This 4-cell kite performs best in gentle to moderate
wind speeds. That's 12 to 28kph or 8 to 18mph. Even in light
winds, this kite will hang in the air, although at low line angles.
In fresh winds, it pulls firmly for it's size, so small kids
should only fly it while supervised!
Every kite design in
the MBK Soft Series satisfies the following points...
- Materials are
plastic sheet, tape and line – and nothing more!
- Tools are a ruler,
scissors and a marker pen - and nothing more!
- All cuts are
along straight lines.
For the greatest chance
of success, I make recommendations regarding the materials. For
example, the type/weight of plastic, type/width of tape and line
type/strength. Close enough should nearly always be good enough,
since the design is well-tested and should be tolerant of small
differences from my original.
Get the e-book for making the MBK Parafoil kite. After making your first one in plastic and seeing how it performs, you can try soft Tyvek or rip-stop nylon for your next build.
The e-book is a PDF file - which means printable instructions to refer to while you make the kite. It also means convenient off-line access if that suits you better.

Having flown nothing for a while and with winds rather light - or so I thought - it was off to a field in Noarlunga to fly the big 2.4m span Rokkaku...
Looking around, the trees weren't doing much so I…
