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.
Probably the easiest way to decrease 1 stitch - knit 2 stitches together as one.
In the video we first knit 2 stitches together in the front loops, the dec leans right.
Then we knit 2 stitches twisted together, i.e. we knit them together in the back loops and the dec leans to the left.
