The Do the Math Sweater is a pattern with two sections: a regular knitting pattern with sizes and specific instructions for yarns meeting gauge and a section where you can pick any measurements, any yarn gauge and with a little math, can create your own pattern! The sweater knits up quickly in the round from the bottom-up, splitting for the armholes, the shoulders are seamed together and then stitches are picked up to make the sleeves and neckline.
