I am using this book for a local scrappy block of the month project. Let me say that I think this is the way to go for complicated star piecing. I would start with a less complicated Carol Doak project if you have never paper pieced before. I completed my first block yesterday and it was challenging, am very happy with the results. It requires a lot of concentration. Do follow Carol's instructions to the letter and purchasing the supplemental disc will make the project faster. I had a problem ordering it, my fault, called her for help and completed the purchase. She is so nice and helpful, was excited to actually talk to her.
