I have taught adult and children classes. While the adult class were 2 - 3 hr sessions, the binding was another class. With the children, classes were like summer camp, 9am - 12noon, Monday - Thursday. They were taught how to achieve straight stitching ( some never did, but they tried and had fun) all worked together as we tied them as they finished the top. By thursday most were finished except for the binding and that is difficult even for an adult, so I bound it for them.
So, please feel encouraged, you do learn as you prepare your classes. You will be thanked by these students, I still receive notes thanking me for teaching them the basics. When they make a four-patch quilt and their friend are all impressed it encourages them to continue with quilting.
