Carol Doak, in my opinion, is the queen of paper piecing.
I have just about all of her books, so it was hard to pick one to review but I finally chose the following.
The designs are easy to understand and the photos aid you in color choices.
Carol even provides a CD to help with copying the designs onto the paper.
Try looking for this book at your local library.
If you are a paper piecer like me, you'll really love this book
