I'm not sure on the end date; a friend said it was through 6/29. If you have (or create, I assume) an account, any one class is free. They normally run $15-50 or so. You can watch them "forever", and the instructor also has a forum for questions.
Sewing, knitting, cooking, woodworking, jewelry - all sorts of crafts. I've never bought one, but have watched a couple freebies, and they seem well done, so I'm going to pick up one on sewing techniques.
