Hi, Mcjeep,
Thanks very much!
I am not telling you that this video is not very useful, but if you have the means (i.e.: money) please buy Ron Edward's book called "Bush leatherwork" (There is a much more adequate book, but it is in my mothertongue, so that would not prove that useful to you). Ron Edwards explains this plait to the full, no questions left. If there remains any doubt after reading it, I would be more than happy to help you in any way (n.b.: the video you linked is about making the 3 plait, whereas - in my opinion - the 5 plait is the real thing. meaning: it covers more, yet it doesn't start to weave itself around, sort of starting to form a half-cirlcle).
