Of course getting an almost 2 year old to pose for photos isn't the easiest task in the world!
I think he likes it though :-)

Original blog post
I used just over 100g of aran weight yarn on 5.0mm needles. I finished it with simple k2p2 ribbing to stop the bottom curling up. If I make it again I think I'll do matching ribbing around the neckline as well. It comfortably fits my average sized almost 2 year old and was a lovely quick knit :-)
The matching skein of yarn is currently otn being turned into a teeny soaker for Bump :-)
