100 gram skein is actually only 92 grams; split into two 46 gram balls to knit socks two-at-a-time. Opted to leave the two balls wound so that the colour patterning will run in opposite directions on each sock.

Used “Tillybuddy’s Very Stretchy Cast On” (page 62 in “Cast on bind off” by Leslie Ann Bestor). Following my usual practice of using 2mm needles to get a nice dense sock fabric and using the numbers from the large size to compensate for that and end up with a “medium” sock.
