DAH I figured it out. I spent hours trying to attach the sleeve. Then I put it all down and went to sleep. All of a sudden it came to me. Now I know what you mean't. I kept thinking what left side. It is a band that you attach everything to. The inside is the neck and the outside becomes the new neck where the hood will get knitted from.
I am going to do it tomorrow. It is too late now to start. I am so excited. I can finish this sweater without going to knitting store.
Where do I go to officially say thank you.
