Summary for Users Who Prefer Quick Info:

You start with a rectangular base made of 12 rows × 12 single crochet stitches. Then you work a sc border around it to round the corners nicely. The sides of the bag are built by doing back loop double crochet rounds to create texture and structure. Next, you crochet four separate shell fan-shaped motifs using post stitches (front and back post double crochet) and double crochet increases to create the signature shell texture. These shells are sewn onto the bag base evenly. Finally, an adjustable rope strap is added at the top, completing your unique sea shell bag!
