Done on small needles in the very lovely Koigu KPM solids - I picked out all the bright rainbow colors with a terrific gray for contrast. I did the bottom of the ribbing (left side) up to about the blue section on slightly larger needles, now I am using smaller to pull in the side of the sweater. Am thinking about making the sleeves and then attaching them at the base of the yoke and decreasing as in an Icelandic sweater...
