Read through the tips and tricks, most of which I did not really understand but I am sure I picked up a few things. Then I read and re-read the first page of this thread; I came to the conclusion that I would not be able to 'knit the knits and purl the purls'. My solution was just to carefully count stitches, easy peasy.
Working on my third project, a simple scarf for my partner. I lost count, but managed to 'read' the stitch on the completed row. Next row I managed to somehow added a stitch which I didn't notice until I had finished the entire row. But this wasn't really a problem since I found myself 'knitting the knits and purling the purls'. (On the following row I just stitched in my new extra stitched in with another so no harm done.)
So, thanks for the great tip.
