Knitting sleeves top-down is a major advantage in cases like this: I only had to rip back and reknit a few inches, and only the shortest rows too. I think the new, shorter version looks better: the net starts in the centre of the panel and blends with the ribbing. (I often write "blend with", don't I? Something of an obsession, I guess.)
Sewing the shoulder strap in place took some time, but wasn't as tricky as I expected. It helps having a nice patch of garden to sit in - and the neighbours came for a cackling visit.
I always block sweaters inside out as I think it makes it easier to get the seams straight. Many instructions tell you to do the seaming after blocking the pieces, but I prefer having the boring bits over and done with as soon as possible.
And here is what the finished sweater looks like. I just can't capture the colour (no 4009), but here is a good photo.
Diana asked about whether the shawl pattern "Leaves Dancing" is available in English. Not that I know, I'm afraid - but at least lace charts are international.
