Do up to row 8 with Mandala and D hook to get 21-ish cm width. Use row 8 to join as you go just like a granny square.

Total count (i think) from bottom up:

bottom row (1): 6 full

1. 5 full, 2 half
2. 6 full
3. 5 full, 2 half
4. 12 full (?)
5. 7 full

9/25 update - used colors from all 10 balls to get the effect I wanted. I omitted a row of the body from the chart I’d found because my torso isn’t QUITE that long. So it ends up leaning a bit but it creates kind of a long collar/asymetrical effect so I’m not going to complain.
