The cables do pull in a lot, and the pattern sucks up a lot of yarn. Consider using a larger cast-on size, or larger needles, and choose a yarn with generous yardage (400 yards might not be enough unless you have small feet).

A note about Dyeabolical’s Super Ego yarn - it’s labeled a sport weight, but I would call it more a heavy fingering. I knit it on 2.5 mm needles and got a very nice dense fabric with it, with pretty much the same gauge I get with other fingering weight yarns.

Named in honor of the children’s book by Shel Silverstein.
