This cardigan can be sized to fit you by simply adjusting your hook size to make the initial large square fit the width of your back! When you do this with a different hook, the rest of the pattern will fall into place.
Thank you for your interest in my pattern! This pattern has not been widely tested, so if you find typographical or numerical errors please inform me so I can correct it.
