I have been quilting a long time and have taught many quilt classes and taken many classes. I also have a teaching degree and know how to prepare a lesson plan. I am upset when I take a class that doesn't have an organized plan and have to pay for it. I have never asked for money back but should have. I also do not take another class from that teacher. The teacher may know a lot but is not organized enough to share the information in an orderly fashion. Good luck in your next experience. Quilting is a building process just like math-start with numbers and progress to fractions, algebra, geometry and calculus.
