Uhhhhh thank you so much for the tip <3 !!! I at first thought its about knitting the old and the new yarn at the same time (I tried this on socks, but it is clearly visible on the right side, not nice) but no, he has a different technique, more like it would be done in colorwork. Why did I never thought of this!!? Is it really secure? Without a knot? 😮
