Cute! Functional! These bags' mesh material allows you to see your project easily, while the snaps provide a snag-free environment, creating a sort of portable yarn bowl that allows you to knit or crochet on the go and is especially useful for colorwork. A zipper pocket on the front of each bag invites you to store hooks, needles, notions, or pattern. The large bag in each set is 9" tall, 11" wide, and 3" deep, and the extra-large bag is 13" tall, 14" wide, and 4" deep.
