I have learned strip paper piecing from Peggy Martin and all shapes paper piecing from Carol Doak. Her video is wonderful as are her books because she includes a CD which allows you to print from your computer and choose the size you want to make your patterns, which is so great. Both ladies are very excellent teachers and each have a wonderful Craftsy class. Try it, the accuracy is so gratifying, and the results - well I've been so happy with each project!
