Finished! Blocked! But warning to y'all: Leave enough yarn for a loose loose bind off! I ran out of yarn in the middle of a tight bind off, then finished up with an even tighter crochet-style bind off. As you may be able to see, the points didn't block out and I have more of a scalloped edge. Oh well, it's still soft and pretty and light as air.
I used three skeins of Rowan Kidsilk Haze, every inch. I used size 5 needles instead of size 3 needles. And I only did three repeats of chart one instead of the five repeats called for in the pattern.

Thank you all for the inspiration, ideas, fabulous photos, and great advice.
