Yes, it is confusing!
Ok. Here's a small picture of the cardigan I'm working on. It's a Fibra Natura pattern done by Helen Hamann. And yes, it is confusing.
You can see on the thumbnail that the sweater has the side and the sleeve all in one piece. You can see the bands (that I've already completed) but you can't see the back...which is what I've completed. Click this for a bigger picture:
I'll work on the side a bit more tonight and take another picture...maybe it will make more sense then.
