Thank you all for the encouraging words! Having made only two quilts since I got addicted to this art form a year ago, the attagirls are inspiring and appreciated.
This tumbling blocks is pieced in strips (Marci Baker's "Not Your Grandmother's Tumbling Blocks").
Also, here is a youtube video about it.

I added the red 'picture frames' and the single row of blocks around the overhang border cuz, being king size, it just seemed to need something to set off those top blocks and break up all that overhang length.
