This pattern is for a granny square bag. I used a worsted #4 yarn and a 5mm crochet hook. The finished bag size was 20” x 20”. the bag can be made with smaller size yarns and hooks if you want a smaller bag. I used roughly 400 yds of Redhart parot stripe, 400 yds of black and 400 yds of white. The pattern includes typed instructions and photos.
