That all in one suit in the Jellytots colour is almost the best thing I've ever laid eyes on. If I could be bothered I'd make myself another onesie in it, but I can't, so I won't. I'm still going to appreciate that this baby gets to enjoy it, though. I love the blanket, I love the hat, I even like the suit on the other side despite the sea-monsterish frill. Doesn't it all just show off that gorgeous yarn so perfectly though?
You'll need 3.75mm and 4mm needles, elastic for the trousers, and buttons for the cardigan and onesie.
