I had been wanting to take a sock knitting course, so I bought it for $29.00 and got a second class free. I took the BOM class. I haven't started the course yet, just downloaded the instructions. It's my understanding that the class is there forever, once you have bought it. I hope I am able to follow the sock course. Knitting socks just seems so complicated to me. I'll see how it goes. I watched the first BOM class and it was very easy to understand. Hope the sock class is, too.
