It’s Innocent’s Big Knit time again! And you know what that means. (Shh… it means autumn is in the offing, but we don’t want to think about that yet.) It means we need to get out our needles and start knitting tiny, tiny little hats, the better to blanket the smoothies of Britain (and, not incidentally, warm some vulnerable elderly folk too). You’ve got two months, so better get cracking.
