I've surfed YouTube today and found a few videos to help you learn to get started with them before the Learn to Knit Socks lesson on the 21st.
DPN video #1
DPN video #2
DPN video #3
If none of these does the job for you just check out the videos that come before or after these on YouTube.
I'm getting excited about luring the lot of you to the sock knitting world, are you?
