from Crochet Me website:

The Halcyon is a soft, rounded shawl with a little short-row shaping to help it drape across the shoulders. The center panel is framed with eyelets – to be woven through with ribbon if so desired. Two versions are shown. The one made with dark rose colored wool-acrylic blend is durable and machine washable, while the white mohair shawl with a ribbon embellishment is more delicate. Using a large hook gives a nice drape to these shawls, they are both very lightweight and surprisingly warm.
