Sure, feministmama, I'll include a video using two colors, with both methods. To work intarsia, you put down the old yarn, pick up the new yarn (usually from underneath the old yarn, so they're overlapping), and give the new yarn a tug, to prevent the hole, and then knit or purl with it. ...I'll illustrate this on the video, (when I finally have a sunny day to shoot it).
