I just completed a two day workshop with Pat Speth, author of Nickel Quilts, More Nickel Quilts, Amazing Nickel Quilts, Big Book of Nickel Quilts (combination of first 2 books) and Borders for quilts. It was amazing! She showed dozens and dozens of quilts that can be made by utilizing 5" squares. Her methods are wonderful and the quilts are beautiful. She is a precision quilter and teaches you how to improve your quilting techniques. It was so much fun and she is a dynamic speaker. She has loads of information on her website and you can download free patterns as well as go to her blog just to get updated information. If your guild needs a speaker I would highly recommend her.
