In terms of materials, there are soft and skin-friendly wool yarns, which are warm and suitable for knitting autumn and winter clothes; and acrylic yarns with a variety of colors, which are resistant to fading, wrinkle-resistant, and耐磨, easy to care for, often used for crocheting dolls and decorative items. In terms of specifications, wool yarns come in 3-ply, 4-ply, and 6-ply options. The 3-ply wool yarn is finer and suitable for knitting delicate and exquisite baby clothes, such as small sweaters and hats, using a 2.5 – 3.0mm hook; the 4-ply wool yarn is of medium thickness and is the preferred choice for knitting scarves and shawls, paired with a 3.0 – 3.5mm hook; the 6-ply wool yarn is thicker and suitable for making warm sweaters and jackets, matching a 3.5 – 4.0mm hook.
