DCM, I don't know where you live, but I see you mention some city names near me. If you want to come to Dharma in San Rafael, I can tell you about the classes there. They have free drop in sessions 4 times a week, not a structured series of classes. We sit around a table and the teacher helps each person individually--anything from absolute beginners to experienced knitters with a mistake to figure out or a pattern instruction they are trying to understand. Some people come with a certain question and leave as soon as they get help; others like me come just to knit with everyone. Once in a while I have a question; more often I help answer other people's questions. If that sounds appealing to you, please come join us! The options are 10-12 in the morning Tues, Thurs, Sat, or 5-6 pm Monday.
Also, to reiterate, lots of people on this forum are experienced sock knitters (including me) and can answer question--but I understand that being in person is a very different experience!
