Well, I'm doing my first one, self-taught. I knitted a bunch of little stocking ornaments, which were pretty easy. I also knitted a pair of fuzzy feet
, which is nothing but a big sock, and now I'm on the first actual, real sock. However, I'm only knitting the gusset now, so it will be a little bit before I can tell you for sure if I did okay without taking a class!
But Silver's tutorial helps, as do the videos on this site! I think you can do it, but there sure have been a few times I thought it would be very nice to have someone in person tell me what I'm doing or need to be doing next.
All depends on how you are with figuring stuff out.
