Scarf - colour change

Making a scarf (my first knitting attempt). Am at the colour change stage. How do I do this? It’s to be a stripey scarf, so need to bring the colour in at the beginning of a row.

Any help very much appreciated.

Thanks, Alice

You can just start knitting with the new color at the beginning of the row and weave in the end later. Our check out the videos in the “More” section–Amy shows different joins.
