Knot Poster Pose

Either start from the ground and lever into a back straddle as seen in the knot inversion video
OR pull over onto the knot, swivel, pull up into seated position, and then lower yourself so that knot is at your lower back right above your bottom
From a straddle back, bring one leg up to the pole, past it on the outside, then in between the two poles and continuing around until foot is hooked (this is crochet)
Bend the free leg, pose
Grab the free foot with either hand or straighten the free leg and place arms out (in any case, pose!)
Un-crochet leg, grab poles high, pull up and sit back up (or pull upright until feet are on the ground)

What does your studio call this skill?
