Oh that's a really pretty blanket! Make sure you share a picture in here when you're done!
I think the pattern stitch you're doing is called moss stitch. What you need to do (if you haven't) is learn what the stitches look like.. learn what knits and purls look like. That way it's really easy to just look at the stitches you've just done and see what needs to be done next. At the beginning of the row you should be able to tell as well. I did this sample to show the difference.
