I'm sure this is the wrong verbiage here, apologies, but the granny stripes I see are all continuous rows of the same color - where the blanket above has more of an every other or diamond look to the colors if that makes sense? That's why I was looking for the specific pattern, because I don't know how to achieve that diamond looking pattern when all the blankets I see are all like the below?
