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. In this article, we are going to work through the process Yvonne used to go from the design of the MQG quilt of the month pattern, Oh Happy Day, and move from design decisions to the fabric components needed. Most importantly, Yvonne shares how she stays organized as she works through this process. Whether you’re writing patterns for sale or for yourself, you won’t want to miss the tips and tricks Yvonne will share in this series!
