These are Nifty Knickers baby longies, from a free pattern on ravelry. Link to my page here. The photos were taken on the same day as these and I am still looking at them and feeling guilty about how tired he looks when I put him through this 'photohoot'!
I had never seen a baby in 'longies' before but noticed them in someones blog (can't remember who now!) and thought they were the cutiest things. They're perfect for the baba in a sling, keeping the chubby legs warm when they're sticking out and reckon they'll be great when he starts crawling too.
I've knit two different sizes as I love them so much. Wooly goodness and baby toes....can it get any better than this??
