The latest book from Carolyn Cullinan McCormick, inventor of the Add-a-Quarter ruler, offers 12 timeless tree patterns that can be made successfully without making thousands of separate half-square triangle units. A gallery of beautiful finished quilts also shows examples of other ways to use the patterns. One look at the beautiful sampler quilt and it is clear that she is gifted at turning timeless patterns into remarkably easy and accurate paper-piecing patterns for today’s quilter. She has even included a brilliant, eye-catching sashing to enhance the center.
