I have taught 4-H quilting to 9-16 yr olds for a few years. We start out simple with a finished 12" block that is made of 2-4patches and 2 6" blocks. They learn to sandwich and quilt by machine and put on a binding sewn to the back by hand. Cannot imagine, as so many people have said, starting with a 9-patch quilt!! So I agree with everyone who said that you need to find out who wants to learn to piece and quilt by giving them a list of supplies to buy first, explaining in a nice way that you are interested in teaching them how but not doing the work for them. And that maybe they are wanting to form a different kind of group than a quilting one.
