I dug through my stash and didn't have any lace weight yarn that would work with the pattern, so I decided to give it a try with some of the sock weight yarn. I'm using size US 9 needles.
Now, I'm not sure whether it's the camera or my monitor, but the yarn is not blue. It is very obviously purple with just the odd hint of blue here and there. Anyhoo . . . I'm about to start on row 10 of the main pattern.
