What is the pattern?

I am very interested in trying to knit this nursing shawl for my sister! Due date is November 3rd! Could someone please help me understand the pattern or where to actually find the pattern. not quite understanding the explanation!

It won’t let me attach or post the link but the pattern I’m looking at is the Revelry: Bloomsbury Nursing Shawl Pattern By Kat Coyle


Looks like it’s from Kat Coyle’s [I]Boho Baby Knits [/I]book, which you may be able to find at your local library or on interlibrary loan.

Thank You!
