These were made with Berocco Comfort Yarn. Size 6 needles, 60 stitches. Next time I would use fewer stitches because I believe this hat will fit a 4 month old baby better than a newborn. However, I know that 4 month olds need to keep their little heads warm too, so I will be wrapping this up for a baby shower this weekend! I also will include the book “Llama llama red pajama” with the gift.
