Antonia asked a great question on her blog about how to keep the shoulderblades on the back when the arms are reaching outward. It turns out my friend, Stacey Mietus, has been pondering just this in her own practice lately. You can check out her musings at http://yogalab.wordpress.com/2011/08/23/minding-my-neck/
Tomorrow in class, set up your blankets and mats as usual, but we'll form a circle for the beginning discussion.
looking forward to it. Am enjoying reading the blogs.
