La Passacaglia Update

I have more progress to show on La Passacaglia.  In the past week, I've taken it from this:

To this:

This is the lower section of the eventual quilt. I need to add a partial rosette to each side to square it up but will do that as I get closer to finishing.  I'm thinking of making some kind of big template the same size as the eventual quilt, to use so I can identify the outer edges.  I want to minimize the amount of time spent piecing sections that will be lopped off when I square up the top.  No rush though; next step will be the upper left quadrant.
