Pieces of Eight E-book by Kaye Wood
16 pages Bulls eye quilts are what this book focuses on and the different methods of putting them together.
Your octagon bull's-eyes have raw edges and will fray with use and washing. The choice of fabric will determine the amount of fray: flannel will fray a lot; cottons less. If the idea of raw edges on your quilt does not appeal to you, there are options for different finishing techniques.
Other tips include borders, layering the quilt, bindings and mitered corners.
