I'm working on a baby item using 3 different colors for stripes.
I was told just cut the previus yarn when I'm changing, but this will leave me with lots of hanging yarn. How to do this correctly?
It depends on how many rows are in each color; if it's just 2 or 4, you can twist them together at the edge where you change colors. If there's more rows per color, then yes, cut them and later you weave in the ends.
