Muhka handknit beanie purchased from the creator and art fair in Mammoth Lakes…preowned but in new condition…only worn once…beautiful hat! Comes from non smoking home There is no tag inside the hat, but it is very soft so I believe it is most likely acrylic. Window shopping and don't have an account?
