Using this Freia Fine Handpaints Solemates Sock Set Yarn is a breeze. Just start knitting or crocheting your sock pattern as usual with the two 228 - yard balls to create those lovely gradient socks. When it comes to washing, it's best to use a gentle, wool - friendly detergent and wash it by hand in cool water. Avoid wringing the yarn out; instead, gently press out the excess water. Lay the finished socks flat to dry to keep their shape. Also, store the yarn in a cool, dry place away from direct sunlight to prevent any color fading.
