Hi, I’m a knitter of 50+ years experience. I have taught knitting for about 10 years. I now have a lady who comes to weekly knitting lessons/help who seems unable to learn the simplest procedure. She has been coming since October of '15. I suspect she does not practice at home but even the repeated hints/help in class should have resulted in progress by now. What can be done to help her? Do I need to try her on crochet? This is major frustration for me and I can’t figure out why she keeps coming if she’s not learning!
