this looks great! I'm hoping you can help me. This is the first time I've used a pattern like this. How many repeats do you do on the back before you start the arm? The pattern says to "repeat pattern throughout" so, I've been doing the pattern to what I thought would be the length of the back. Now i'm not sure. should I have stopped after the first 9 rows and done the switch, or do I finish the back and then move on to the front? Thanks so much for your help.
