Hand-knitted ☆ Opal Yarn Knit Hat I knitted a hat with a Fair Isle pattern using cute Opal yarn sock yarn and mohair. Although it looks like Fair Isle, it's made with a single yarn, so the back won't snag. Shrink-resistant wool, nylon Depth: Approximately 21cm It's a thin, light, but warm hat. It can also be used as a care hat during hospitalization or treatment. Hand wash recommended. Dry cleaning is recommended. Do not use bleach or fabric softener.
