Since I am not formally trained one of my goals this year was/is to work my way through several design and color books. Right now I am reading Color and Composition for the Creative Quilter by Katie Pasquini Masopust and Brett Barker.
This was an exercise in Monochromatic Color Schemes. One of the things I am really enjoying about this book is that she encourages you to use your photos and drawing to make art quilts.
