Cast on for medium, 12 repeats of ‘A’ pattern and then bound off for arm section, then for body, 3 repeats of ‘A’ and then two of each of B-E (18 stitches between purled sections), total of 11 repeats down back. I increased the same across every panel, so the back and sides increase at the same time.

For reference, I am about 5 foot 11 inches tall.

If I did this again, I would cast on fewer sleeve stitches and perhaps finagle short rows or a gusset to raise the back band.
