Sara Nephew is a nationally known teacher and is the originator of a series of tools designed for rotary cutting isometric shapes. This book was planned for ease of use, with an index in the back to help you find particular cutting directions. The quilts are organized in order with the easiest patterns at the beginning of the book and the most challenging at the back. I found this book easy to use and had smooth sailing with the patterns. Most of the quilt designs are pieced with all straight seams. So, even if you're a beginning quilter you should be able to find a number of patterns you can put together without problems.
