HI, I just got a new book, Doubledipity: More Serendipity Quilts by Sara Nephew. It's an older publication, 2006, but it is still available. Basically she takes a kalidescope hex block (OBW) and adds additional piecing to make a larger block. This is a great way to use up all those pretty blocks you made for your OBW that didn't fit into your design. She also has a lot of border patterns. If you have left over OBW hexes, or just like kalidescope blocks, you might want to check this out.

Thank you, I will look into this book :D:D:D
