@Acorn you're right. I don't seem to have much trouble with a cable pattern as it is bold, and quite easy to see. The pattern I'm doing now is quite a subtle diamond pattern, and it's easy to miss a wrongly facing stitch.
I'll keep trying with the small area correction, after all, the worst that can happen is that I have to unpick the rows anyway. I just had difficulty yesterday, as to correct the stitches, they have to be twisted...
I do wish that when these tutorials went on YouTube (or similar), they would show a correction with a pattern.
@Ouryve , I do use a crochet hook, as it make things easier, but it's the manipulating of the stitches I find hard.
I think I just use patterns which are above my pay grade...
