Although I admit to being a big EB fan, there are a couple of books in my library I wouldn't be without:
Rotary Magic by Nancy Johnson Srebro covers rotary cutting techniques and her instructions for the quarter inch stop are awesome
Quilters Complete Guide by Fons & Porter covers just about everything quilting - very helpful if I run across a new to me technique and the instructions for drafting are invaluable. If it's something new to me, this is the book I turn to first.
Quilts Quilts Quilts by Diana McClun and Laura Nownes - another very good, comprehensive quilt book and very easy to understand. Lots of great quilts in this book.
Joanie's Quilting Elements by Joanie Zeier Poole covers machine quilting and helped me understand some things that had eluded me. The book comes with some machine quilting pdfs - a nice bonus.
All that being said, I admit to having 27 Eleanor Burns Books :oops: You just can't beat what works - and for me, her books work.
