I cast on May 1, and zoomed along until Thursday night.
Yep. Ran out of yarn with half a row and the bind off to go. (This is definitely a case of "losing a game of yarn chicken".)
Luckily, I picked up a nearly-the-same-green sparkly lace weight at Uniquities during this April's Metro Yarn Crawl.
It worked! It's blocking now, and the pattern is fun enough that I plan to start another June 1!
