You can see two very neatly worked braids in the picture below. In fact, every braid consists of two rows of right- or left-leaning stitches and, depending on the arrangement, your whole braid can point to the right or to the left. And the good news is, you can work it in more than two colours!
There exist several good videos showing how to knit a Latvian braid. Here is my favourite one:
And here is my homework – all done!
Good knitting everyone!
