Last year, Marly Bird approached me about designing a square for a wedding blanket she was organizing for Ally, our contact at Red Heart yarns. Marly and her team also coordinated a crochet along so that you can have the chance to crochet your own version of the blanket! Find out more about the Wedding Blanket Crochet Along and get links to the rest of the patterns here.

I don’t crochet as many twelve inch squares as I crochet six inch squares, so I decided I would make a 9-patch square that includes nine smaller squares joined together. The Pattern Notes give you links to four different tutorials for methods to join your version of the Great Star Coral Square.
