Like tongues of fire, lightning bolts of maize and dark blue streak across a background of ardent red. Alberto Ruiz weaves a bold design in virgin wool. Named UniĆ³n de Diamantes in Spanish, the traditional Zapotec rug is created on the handloom and takes its fiery colors from natural dyes. Because each rug is individually woven, measurements could vary +/- 4 inches (10 cm).
