Sparta sweater is worked from the top down. First the back is worked back and forth. Then, pick up and knit stitches along both shoulder seams and work the two shoulder sections separately. Join the shoulder sections by casting on new stitches at the center front and finish working the front section. Then you join the work to knit in the round using two colours. The colourwork is charted.
Once the body is finished, stitches will be picked up for the neckline and sleeves.

I choose a needle 0.5mm larger when working the stranded pattern to maintain the same gauge as when working in stockinette stitch. It is different from knitter to knitter whether or not your gauge changes when you’re knitting with more than one color
