Yay! The sock blockers have arrived!
While ordering, I thought I'd order some of the beautiful Caspian wooden needles in my most-used length (10") and sizes (4mm - 5mm). Also a 2.5mm fixed circular needle.
Here's another close up of the interesting, yet easy to execute, pattern. It's a checkerboard background with a superimposed trellis.
I did find a helpful hint for casting on the tab at the neckline of a crescent-shaped shawl. It is all explained here. Susan's Sweet Dreams Cast On is outlined here.
The Sweet Dreams shawl is actually the one I was thinking of doing. I may just bite the bullet and buy the Boo Knits collection.
