My friend Lacy just became an aunt. Her nephew was born very prematurely on Christmas Eve in Australia and she wanted a hat for him. Although he weighs just over three pounds, his lungs seem to be doing well, so things are looking hopeful.
One of the preemies web sites says that hats for premature infants should fit an orange. It felt more like casting on for a sock.
It was such a quick knit I tossed in one to fit a grapefruit as well, to grow on.
