In each issue of the MQG Journal this year, Yvonne Fuchs will be sharing an important behind-the-scenes aspect of quilt pattern writing: quilt math.

We will discuss how to take the information in them to determine which of the construction methods would be best for the quilt or quilt pattern you are creating.
