Thank you for looking. This is a hand-knitted hat. Material: 100% Acrylic Diameter of opening: approx. 20cm Length to crown: approx. 22cm Weight: approx. 70g How about a warm hat for these still cold days? I think it would also be perfect as a gift. However, please understand that as it is hand-knitted, there may be some unevenness in the knitting. For washing, I believe it can be machine washed using an all-purpose detergent and a laundry net. Do not use a dryer. A label with washing instructions will be included. Thank you. #Handmade #Hat #Warm #Cute #Lightweight #Knit #Handmade #OneOfAKind #AnonymousShipping #RedTweed
