I have that same book and working on the first sock pattern as well. I figured out how to pick up gusset stitches and work the heel. I am about half way down the foot and noticed something.
Where the 2 needles seperate there is an obvious "flaw" in the sock. I try to pull the yarn as tight as I can to keep everthing even. However, I still notice it. Not a big deal I suppose, but is there a way to get the 2 needles to match up a little easier? or does it just come with practice. This is the first sock I've ever knitted.
