Hexagon quilts are popular and have been for a long time. That's the idea behind Recycled Hexie Quilts: Using Vintage Hexagons in Today's Quilts by Mary W. Kerr. She's combined fragments from unfinished quilts with vintage embroidery (or newly pieced blocks) to make a whole selection of quilts, giving new life to long abandoned projects.
The book includes a timeline of finished hexagon quilts that is absolutely breathtaking. I didn't realize that there were so many possible layouts!
My favorite line from this book -- "Ignore the quilt police -- they are not invited to your party."
Disclosure - the publisher provided me with an electronic ARC.
