I knitted up very quickly this newborn hat for my grand daughter Hannah whom was born on August 6th. I used up some cotton sock yarn that I had leftover. I did a lace design throughout the hat. When I went down to visit, I put the hat on her. Well let's just say that it will fit for a week and that is it. Either the hat was way too small (tight knitter) or the babies head was bigger than a newborn sized head. Who knows? So it was nice while it lasted.
