Aren't you glad you moved forward? Every project you complete will be more practice, and you have the satisfaction of completing beautiful work. We are never done learning and getting better, but, to me, it doesn't make sense to just keep on practicing on scraps. The tip that has helped me the most with FMQ meandering is to visualize going around the size of different coins. I do dime, nickel, quarter, and fifty cent size meanders. It helps to keep the size consistent throughout the whole piece.
