After a reset on the side, I started with repeating the clusters from the top.
Still doing the repeat, with a mirror image of the top.
For a new attempt at the side, a departure from the clusters. Note that joining at the picots was necessary. I started without the joins but that let the work flop and fold around the side, so I redid the work making all the joins.
Put onto the pincushion, this side pattern repeat seems to be working.
This is not enough to complete the pattern, I will need additional row(s) for this pattern.
