I need help understanding the next step in making my cardigan. It is the Imperial Yarn Arrowhead Cardigan. It is worked in the round with two colors. I have finished the armhole streaks and binded them off and now I am confused on the next step. It says to rejoin the yarns to begin with a wrong side row. Am I suppose to purl this side to keep the pattern on the right side? Am I still working in the round? Will someone please explain this in a little more detail?!
