One ball of Opal yarn used! It's finished fluffy and soft♪ Since it's sock yarn, it's light and can be used until early spring ^ ^ Size: Free size Care: Since it's knitted with sock yarn, it can be washed in a net at temperatures up to 40 degrees. When drying, shape it and dry it flat. Note: It is carefully knitted, but it is handmade, so we appreciate your understanding. #sockyarn #opal #opalyarn #yarn #handmade #knitting #knithat #handmade
