From Page One of the pattern:

Most of the techniques used for the Allium Pullover can be found in traditional stranded knitting, but there are non-traditional touches, too. And, there are many points at which you can make it uniquely yours.

The Allium Pullover is knit circularly using no more than two colors per round. Every size uses full motifs. Because the motifs are large and the design is symmetrical, instructions based upon the sample’s gauge are given for only three stitch counts. But, instructions, statistics and layouts for both the sample’s gauge and a slightly looser gauge are provided, giving you six chest sizes that work with the same yarn. Two lengths in each of the two gauges are given for the body. Sleeve lengths include both the usual, wrist-length option and a longer, mid-hand version (for my “cold hands, warm heart” friends.) The decorative bands on the shoulders and sleeves are easily modified, giving you yet more ways to fine tune your pullover’s fit.

You will find lots more information about this design on the Allium Pullover page on Mary Ann’s website, here.
