PART 1: side closer to the neck.
In the next picture I pinned picots that are going to be joined: I started joining from pin number 1.
This side, all rings are 3-3-3+3-3-3 (5 picots, considering a join "+" as though a picot). Rings join to square motifs in their central picot.
Then they are all repetitions, till the last square, restarting from pic 1.
