I can't recommend this pattern wholeheartedly, as there were errors in it. The sleeve decreases are wrong - if you followed them, you'd end up with sleeves hanging down near your knees. The number of stitches at the cuffs do not work for 2-2 rib in the non-cable sleeve. The pattern instructions for the button bands are the wrong way round (since the buttonholes must go in the left hand overlap, to be on the cable side of the front).
The finished item is, however, really lovely. Even my hard-to-please 14 y.o remarked it looked like something you would buy in Topshop. Now that really is praise, as it's her favourite clothes shop.
I especially love my buttons, which I bought at vast expense in John Lewis:
I could, optionally, add facings to the button bands. I bought some embellished organza expressly for this purpose, but now I'm wondering whether it will be easy to sew button holes in sequinned and embroidered fabric? Also, I think it might make the garment a bit too seasonally festive, which is OK right now, but probably not so good in January. So I'll have to think of something else to do with this:
I have half a metre. If anyone has any suggestions, do let me know.
