There is a Danish word, "flette", that means to plait something, and I always
thought those flets were in fact made of interlacing branches or something like
that. I'm not sure whether the word flet made me believe so or if it also said
something about it (I don't have the book at hand right now), but anyway, it
would seem natural for the galadhrim to make their flets that way.
So there may be a connection (maybe through Anglo Saxon as NZ Strider
mentioned, or more
directly)
