Ok, here’s what must be a silly question.
I just started knitting and my first project is a scarf (surprise, surprise). It’s charcoal grey with a couple of cream colored (actually “wheat”) stripes on each end. So, while reading in my “Knitting for Dummies” book about how to switch colors I ran across the recommendation to carry the previous colored yarn up the side of the knitting instead of cutting and dropping the old color when starting the new. However, the instructions for doing so are somewhat vague and are paired with a diagram that appears to directly contradict the written instructions. Can someone explain to me how to do this or point me at a website that can clarify this apparently simple technique.
