Yes, granny squares are usually worked in the round. They often start from a central ring or a few initial chains that create the center, and then crocheted in rounds, adding stitches along the edges to form a square shape. The traditional granny square begins at the center and expands outward in a circular fashion, often with chain spaces or clusters of stitches that create the corners and sides of the square. The round-by-round construction is what gives the granny square its characteristic look.
