Posted:You just let your poi tethers spiral wrap around each other right where they leave your hands, then cross over to the other side, unwind it all with a little circular gyration of the hands, then wind-em up on that side and repeat. I say "just" but it isn't totally easy... takes some work on controlling the tangle and crossing it over... These are therefor not infinite, just "really a lot".
If you get good at hand switching your handles in split-time chase, then you can do that for an arbitrary amount of time on either side of a crossover... but this doesn't seem like you are weaving really, since you are constantly resetting any twisting.
To me a weave is twist -> crossover -> untwist -> twist -> crossover etc.
