From Knitty:
This beautiful wrap, designed by Kaffe Fassett, uses the candy of the yarn world: Kidsilk Haze. Riotous color is Fassett’s trademark, and in this simple-yet-striking striped wrap, a generous assortment of colors is arranged to dramatic effect.

The wrap is a generous size, big enough to wrap multiple times around a neck or lushly around your shoulders. Knitting it will be half the treat.
