Yup I watched that video! It doesn't show the first and last stitches. I wish it showed the cast on. What I did was hold both colours together cast on 2 together then alternated between colours to cast on. I understand how to get one colour on one side and one on the other but it's the slipping of the stitches and then knitting with both colours at the start and end of each row.
Also it's a little confusing the follow the pattern. There seems to be 29 stitches across instead of 30. So I'm confuses about when I do red and when I do white, and if when I do red should I be doing red on red or red on white.
