interesting and a good idea to post videos about planes, as they are very important.
I find that when I teach poi, i usually describe planes as their relation to the body and encourage people to envision being inside a box, with sides, front/back, top and bottom (which would be under your feet).
for example, when forward spinning with the poi at your sides, this is "side plane." When doing something like the butterfly or thread the needle, this is "front plane" (or "back plane" if the poi are spinning behind you. You can also have overhead plane, like for a corkscrew maneuver.


it is interesting that many spinners have their own lingo, and that is part of the beauty of it!
nice work. hope we see you soon!
