Thank you for viewing. This is a kids' size, approximately for ages 3 and up. I knitted a basket-weave hat using melange tricot (pink) yarn. 100% acrylic I made this to fit my 3-year-old (head circumference 50cm). I have my child try it on to check the size. This is a handmade item made by an amateur who is just into knitting. Please purchase only if you understand that it is handmade. I referred to a video by mimiamu.
