I've taught several beginner quilting classes in 3 different states. Quilting is a skill that is LEARNED!! You will get better the longer you work at it and the more you work at getting better. My first quilt was so bad that I threw it out before it was finished...... and I'm a VERY good sewer!! I didn't realize that sewing and quilting are very different. There are so many techniques to learn with quilting to make it easier, or just plain more perfect if you want your projects to be more perfect.
I'd say, find a different teacher. It sounds like there are more shops in the area..... seek out one that has classes you will enjoy. I always wanted to turn people 'on' to quilting....... but for sure, I didn't want to turn them 'off'.
