Handmade baby-sized acorn hat. Material: 70% cotton, 25% acrylic, 5% nylon. Size: SS Head circumference: ~44cm Flat measurement: Opening: approx. 19cm Height (excluding the pointed part): approx. 14cm Slightly stretchy. It's also cute to fold over the opening if it's too big. This is a handmade item made by an amateur hobbyist, so it is not perfect.
