Each color I use comes from natural dyes and has a particular symbolism, explains Zapotec weaver Alberto RuÃz. The colors are meant to replicate nature, so grays resemble cloudy days, green the Oaxaca hills in the summer time, and red reflects our sunsets. RuÃz weaves this wool rug on a traditional loom. Because each rug is individually woven, measurements could vary +/- 5 cm. Because color is obtained from natural dyes, tones may differ slightly.
