This advanced beginner crochet moss stitch scarf uses the extended moss stitch, a textured two-row repeat worked flat in rows. It is made with worsted weight (#4) yarn and an I-9 (5.5 mm) crochet hook. Double crochet stitches are worked into skipped stitches two rows below to create the woven texture. The finished scarf measures approximately 4.5 × 60 inches (11.5 × 152 cm) and uses about 300 yards (275 m) of yarn.
