I gave the sweater some waist definition by working decreases in between each cube over three cube repeats; this gives a subtle, yet figure flattering shape.
This particular slipped stitch pattern adds a bit of a twist to the equation: you have to change color every row. That means you have to use a circular needle (unless you enjoy slipping all your stitches back to the end of the needle), even while working in rows, to have the ability to turn your work at will. You will also have to work two consecutive right or wrong side rows, all depending on which end of the piece your next color is lying in wait.
