Magic Loop is a mystery to me. Recently I thought, "I'm going to figure out ML." So I went to a site that shows pictures of how to do it. I thought it looked easy, but I couldn't get it to work.
I think I am one of the people who will prefer a really long needle as opposed to a short one. I don't have one, and I don't have the super flexible cables.
I consider myself a slow learner and that ML thing I will have to see in person to ever get it. Maybe video, but with my slow computer I hesitate to use them much. You're lucky you will be able to take a class. I hope it turns out to be as easy as everyone says.
