I've taken some great classes and some not so great classes. The not so great classes are the ones where the teacher doesn't have enough time to teach what needs to be taught so she hurries through everything and leaves everyone scratching their heads at the end. That's when I wish I could get my money back. I took a paper piecing class and it was only 2 hours long (I knew nothing about paper piecing and didn't know 2 hours was not enough) and left with half a project finished and couldn't finish it because I couldn't remember how to finish it.
