After cutting through the steek it turned out to be 96 x 90 cm, without the border.
The stray blue sheep was an idea I saw in another project on Ravelry. I did work it in intarsia in the round, which is a very fiddly way of doing things, but it couldn't be helped.
The only issue I face now is that I'm going to run out of yarn (this border is eating up yarn, like there's no tomorrow). So, another trip to the yarn store is in order.
Oh, the hardship ;)
