I would suggest straight line quilting with vertical lines from top to bottom, with each line cutting the block, more or less in half. So, if the center units are about 2, then quilt 1 from the seam. For the next unit, if it is between 2 and 2.5, I would do a strait line about 1.25 from the edge (about 2.25 from the last line). And continuing in that manner making the lines strait and coming close to bisecting each unit but understanding it wont be perfect. As you can see from my photo, my lines are NOT equidistant.
2 more options.
Horizontal lines bisecting each strip, more or less.
Curved horizontal lines.
As to thread, one that is similar to your gold might be lovely.
