Our videos do not have sound. We are a worldwide company and our videos are watched by people speaking endless of different languages and many do not understand Norwegian. So since there is not a given language for us to use, we instead have written instructions to accompany the video, and then there is no sound to disturb while watching.
When you knit stripes you can carry along the yarn not in use along the edge. This way you don't have multiple thread ends to fasten afterward. Before each new row from RS twist the working yarn around the tread/threads not in use, and then continue.
