Well, what do you know - I finished it:
That must be the fastest I've ever actually finished a class piece.
Now I'm debating with myself whether to stitch it again, this time in the green colourway, cos in class that just looked so good. I mean, I like this colourway too, but the green was just spectacular and if I'd seen them in person before choosing the colour rather than just a slightly blurry picture I'd have gone for the green. Or the colours are really easy to change so I could choose my own colourway.
