Opposites Attract may be one of the easiest patterns I have ever written. It is very simple design that uses knit, purl, and yarn over stitches as it grows into a lovely crescent shape, that is maintained even without blocking.

Ensemble Light is used in 2 opposing colors, 400 yards of each, but the pattern is versatile and can be adapted easily to more or less yarn.
