Traveling quilters who hand piece complicated quilt blocks (I know, everyone is rolling their eyes now), can use their larger flat batting scraps as pages in a book. Page size will be determined by the largest block you piece. Stack the pages and sew along the left side to make the book. Pin one complete block in its proper layout per page. If the pins face vertically, you can roll the book up and tie it with a ribbon without getting poked. Otherwise just tie the open side of the flat book with attached ribbon. The book pages are good for storing the finished blocks until all are completed. This method is also good in 'loose leaf' form for anyone who belongs to a hand piecing Quilt Go Round group where each person is working on one of your blocks.
