I have to say, the class was really clear and simple to follow. I don't think I would have ever got around to knitting a sock if it wasn't for that class. It was Craftsy's 'My First Toe Up Sock' with Susan B. Anderson and I would definitely recommend it for a beginner. Full instructions are given from measuring your feet correctly to finishing off the socks. You can see how stitches are formed thanks to some great close up work. I could see exactly what I was meant to do - and that is great when you are doing something new for the first time. A full written pattern is also supplied in the course materials.
This is my first pair of socks but I have already bought two other lots of yarn in order to knit more. This one is in double knit/worsted weight superwash merino. It is lovely and soft and cozy. The second will be in the same weight of wool but brighter colours (pink, purple and lettuce green). The pair after that will use Arne and Carlos' self patterning yarn. It is a finer weight and uses smaller needles. That will be a whole new challenge.
As for stopping my hands hurting while knitting - I discovered the Norwegian way of knitting. It is much like Continental knitting but with slight variations. The stitches are worked much closer to the tips of the needles and the movement is all in the finger tips instead of the whole hand and wrist. Arne and Carlos have a nice little video on YouTube where they show the basics. Definitely worth a look.
