If you have only 9 weeks, you'll want to make sure that you will have a completed project at the end. So, would you take 1 week to introduce their sewing machine to them, 5 weeks to piece the quilt, 2 weeks to quilt and 1 week for the binding? You will have to judge the slowness or fastness of learning from the class to determine this. I know at the end of the 9 weeks I would want a completed project.
