From the pattern page:

Granny square lace? Absolutely! This lovely cashmere and silk lace-weight yarn works up beautifully following the directions for the Popcorns and Lace Square. Finishing this shawl is a breeze, too, because you simply stitch the squares together in a long V shape. I added a scalloped edging to finish it off. Light as a feather and warm as a hug, this shawl is truly a dream to wear.

This shawl requires 20 of the #55 Popcorns and Lace Squares (page 90). The square pattern is both written and charted.

Assemble the shawl using the seam method shown on page 26. The instructions are both written and in a simple photo tutorial.

The two row edging is a Three Petal Scallop which has only written instructions.
