These antik Bolivian hats are called Chullu's. They are traditionally hand knitted by a boys father while the mother preparing to give birth. Each Chullu is wildly colorful and has a pattern of it's own, so they are sold as a one of a kind unique item. The sizes are all different so if you have a measurment please send me an email and we can discuss which chulla will work best for your baby. These look great on both boys and girls! 100% wool super fine guage and not really itchy!
