I found the reason why I was going to restart this, but, as so many more stitches when in, I've decided to get friendly with the seam ripper, and take out the offending block of stitches. I'm doing bit by bit, so it doesn't get too disheartening.
At the same time, work on the hands has been going on. It's really a weird sensation to walk past and see the hands appearing like this. All the confetti stitches and the bad chart seem to be a small price to pay.
It'll be interesting to see what changes there will be after another week.
