Using the term "exploring" makes me think this class may be more of a discussion about machine applique than a actual class.
"Exploring and learning the art of machine applique" as a title, I would think I would learn about the different techniques and be taught how to do them
I see many struggle with satin stitching, and using a blanket type of stitch around tight curves and points. Spending time here letting the students practice would be very helpful.
Maybe show examples of:
The difference in using a stabilizer or not.
The difference in fusible products.
Good luck with your class
