I didn't take a closeup of the top and bottom borders, but if you look close you can see that the triangles that she whacked off the 9-patch blocks make up those borders. Ingenious!
I rather like how the quilting design mimics the swirly things from afar. I chose Turbulence panto, Honey PermaCore thread and Hobbs 80/20 batting.
Some closeups.
