Here are my two new favorite books that helped me "get over" the scrappy coordination hurdle. I got them through my local library's INTER-LIBRARY LOAN program - I was able to read the books and try a few things before buying:
Simple Strategies for Scrap Quilts by Lynn Roddy Brown
Published by That Patchwork Place in 2006
ISBN 13: 978-1564776853
Simple Strategies for Block-swap Quilts by Lynn Roddy Brown
Published by That Patchwork Place in 2009
ISBN 13: 978-1564778581
Each book approaches the "problem" from a different angle. I joined an on-line quilt block swap group that swaps every other month, and participation is optional. The coordinator posts the schedule of swaps which set forth the size, color, theme or whatever of the swap. ALSO, this book helped me use up my fat quarters in such a way that the resulting nice-looking quilts are scrappy without any swapping. (Does that make sense?)
