I agree that it is important to show each step of the way and have a sample of each step on a board so that even the beginners are able to see how things come together. My friend and I are teaching a class in Sept. and decided to teach a 'simplified' version to learn the technique. Once the students have the technique down, perhaps sewing a sample from their stashes, they can go on to duplicate it on premium fabrics.
good luck; it will be fun and you'll be surprised how fast the day will go by.
