The Lunar Halo Granny Square is a 6x6 inch square when worked with a 4mm hook and Worsted Weight Yarn. When done in DK and a 3.5mm hook, it’s approximately 4.5x4.5 inches.
This square was created specifically to compliment The Man in the Moon, Here Comes the Sun and Luminosity Granny Square Squares. They are the same size and have the same stitch counts on the last few rounds to pair them perfectly together.
