Carissa Knits: Preemie Hats for Charity - my favorite baby hat to knit. Good for newborns and the pattern is very easily adaptable. I cast on 80 stitches and used the Flakey Baby Sock pattern from Jujube and Lolo.
Now I just need a little girl to knit stuff for!) *** Twenty Something Granny: Knitted Baby Bow Hat. Looks like the bow piece needs to be a little bigger so it's fuller on the finished hat, but this is so adorable!
