Following others comments, I made the neck longer - 22 rows of rib - which has made it fold over nicely.

I also wasn’t completely convinced by the need for the moss stitch at the bottom of the cosy, so I just did a three needle bind off straight on the bottom of the cable pattern. A total of 10 repeats of the cable in all.

Really pleased with this.

Added a white ribbon round the neck after I took the photos, which set it off perfectly.
