Refractive Socks

These socks are worked toe-up to use up every bit of handspun yarn. The refracting wave pattern is somewhat illusory - on the chart, it appears that the stockinette portion is wandering back and forth on the ribbed portion, but on the sock the ribbed portion appears to be wandering on the stockinette portion.

Errata: The chart is correct, but on the chart key the symbols for k2tog and ssk were reversed. Version 1.1 (6-27-2012) is correct.
