This perfect newborn baby hat is knit flat, on 2 needles. I find this much easier when working with such small hats. This "first hat" is designed to fit baby while in the hospital, this pattern includes 3 sizes to cover all babies. Small Preemie, Larger Preemie, and Newborn (0-3 months). Makes a GREAT shower gift, or hospital gift! Knit with sportweight yarn, this hat is great for all seasons. Details include attractive striped texture, smooth ribbed brim, and an optional top knot (directions for with and without are included). This is an easy-to-read 4 page pattern with full color photos. Sizes: Newborn (0-3 mo), Smaller Preemie and Larger Preemie (ALL included!)
