This is an opposite direction in butterfly, anti-spin vs. extension hybrid. Grab your poi and open your mind to a new trick.

start by spinning your poi in an over hand butterfly in split timing. One arm is going to extend around the circle and as your arms cross, the arm that is extending will stop the motion of the arm and head back the direction it came, now anti-spinning a flower on the way. The other arm in now going to extend and follow the anti-spinning arm. As the extending arm crosses over the top of the other arm, it stops the motion of the arm and goes back along the same track, now anti-spinning.

Now repeat over and over. You will need to have your poi slightly shortened so as not to hit your arm as you cross over the top.
