I think it's wonderful that you're considering teaching. I'm a little disappointed in the range of classes offered by the local quilts stores. Bringing in "new talent" could greatly increase the number of students taking classes.
I'm usually motivated to take a class when it presents a new technique. Right now I'm looking for classes on landscape quilting, or other types of art quilts. I've done some paper piecing but might take another class if it included more complicated designs, as yours does.
Your jacket is beautiful, but sadly I wouldn't be interested in the class because I'm not interested in making garments, especially if it involves altering patterns. I think you may find that's typical of many quilters, so if you intend to teach several courses it might be good to have some that don't involve garment sewing. On the other hand, you might find a real niche in the market by offering jacket classes, even your own quilted jacket patterns.
