I've posted an image of a sweater from the Eddie Bauer website. The knit stitches seem to flair outward toward the top of the color, while the purl ribs seem to taper. Is this accomplished by purling each pair of purls together a row or two before the end? Also, looking at the sweater in the store (I would have bought one but they didn't have my size), I got the impression that somehow the binding off was done in two directions, with the left knit stitch of each pair being bound off over the stitch to the left and the right stitch being bound off over the stitch to the right, helping to create the flair. Does this make sense? If this is what's happening, can it be done by hand, or does it require machine knitting?
