So that nine-patch of circles minus one became what I originally intended:
a cover for my Juki sewing machine.
It took a little engineering, but it fits.
Here's the back where I made room for the thread stand
by removing one block, as shown in the previous post.
I used Kona Espresso for the backing and the binding, and
some off-white Kona for the background.
Thanks for the March challenge that pushed me to finish this!
