From the pattern website:
This baby wrapper & hat set makes a great new-baby gift. I especially love using organic cotton for newborn items. Blue Sky Alpacas organic cotton is about the softest yarn you’ve ever felt, and of course it’s grown without pesticides and other nasty chemicals - good for the environment and a delicate new baby. The openwork pattern used here is also easy to memorize, so it looks fancy but is simple to work.
