Handmade hat by a craftsperson, made with 100% cotton yarn. The size is 40-42 cm, suitable for babies around 2 months old. My baby was born in the summer, so they outgrew it quickly, and it was only worn a few times. It shrinks in the washing machine, so it needs to be gently hand-washed. Please consider purchasing if you don't mind a pre-owned, hand-knitted item.
