Aren't these just the sweetest, funniest things? I can see any kid just loving these but they're also going to appeal to geeky parents too I reckon. They're written for the King Cole Comfort Aran and I think the King Cole Forest Aran would make a really great option for more subtle colours. You'll also need some Dolly Mix for the details.
This pattern uses 4mm and 5mm straight needles.
