I forgot to mention with that last double knitting method that you need to do it on circular needles, because the yarn will be at the wrong end to knit with, so half the time you will need to slide the work to the other end to begin the row.
Or, you can do two rows in one color (knitting, then purling, and slipping the opposite color each stitch), and then two rows in the opposite color.
