Like many sweaters, woven, KNITS, woolen, and KNIT are all fabrics used to make sweaters. Woven is a fabric made by interlacing two sets of yarns or threads at right angles to each other. KNITS are fabrics made by looping yarns together in a series of connected loops. Woolen is a type of fabric made from wool fibers that have been combed, carded, and spun into yarn. KNIT is a fabric made by interlocking loops of yarn. All of these fabrics are commonly used to make sweaters.
