This just clicked for me last night!
The only problem is, the yarn I'm currently working with is dark dark dark purple and so it's still hard to distinguish one stitch from another unless I go slow and have a really bright light shining directly on it. I now know what the stitches are supposed to look like, I just can't see them, heh. So until I'm on another project with easier-to-see yarn, I'm stuck with keeping count in my head, "knit, purl. Knit, purl." lol!
But this tutorial really helped me get it. I still can't distinguish end stitches, but the ones in the middle of the row I can tell apart.
