As I predicted, I finished this piece - there was very little left to do. Which meant that I finally got around to picking up the angels piece (aka Christmas Nemesis).
I've done a small amount of filling in, in the centre (still some to do, but it's fiddly, a few stitches here, a few there) and have made good progress on joining up the border. I will probably only stitch on this one another week - there's a small piece I'd like to finish as well before the holiday spirit leaves me. And anyway, it wouldn't be Christmas without the angels, so I wouldn't want to actually finish the piece!
