What Matters: Investing in Results to Build Strong, Vibrant Communities is a joint project by the Federal Reserve Bank of San Francisco and Nonprofit Finance Fund that features essays exploring the possibilities of an outcomes-based world. The design challenge was transforming the book’s theoretical investment concepts into descriptive visual imagery. C&G Partners used String art, created through craft-based techniques, to emphasize the book’s human-centered approach. Using a branded color palette of blues and oranges, the cover illustrates how straight lines can be woven into a curve. This design process echoes the book's focus on how outcome-based collaboration—instead of an output-based approach—results in positive, long-term impact. "Our stinging metaphor reinforces the motif of collaboration with a common goal that is greater than its parts." At the heart of this book design is the idea that the ‘insignificant’ straight lines when focused on a shared outcome lead to something coordinated and complete. The cover image was developed through an iterative process, experimenting with various mathematical compositions of string weaving to arrive at the best layout. The building process is further explored in the chapter dividers of the book, each section featuring a different stage of the string weaving process. The publication is the fourth in a series of book designs by C&G Partners for the Federal Reserve Bank of San Francisco.
