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.

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
