This product is handmade. I knitted this hat using a crochet technique called "basket weave." Being hand-knitted, the fabric is thick, resulting in a very warm hat. The pom-pom is made with fluffy yarn and has a very cute finish. Yarn: Melange, 100% acrylic Color: Pink Size: Since it's knitted, it has some stretch and should fit children aged 6-10 years old. Approximate measurements: Width: 20 cm Length: 20 cm (to the top of the hat, excluding the pom-pom) Pom-pom height: 5 cm, width: 6 cm Thickness: Approximately 5 cm, making it very warm. The last photo shows a size comparison with an adult-sized hat. Please refer to it. If you have any questions, please feel free to contact me.
