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.
A new pattern for a baby hat. I saw this stitch on a baby cardigan pattern and thought it would make a cute hat. The pattern is written for a newborn, but increasing the cast on in increments of 12 will work to make larger sizes.
