The Decolorized carpets are knotted by hand consistently with the tradition and subjected to a decoloration process followed by re-dyeing with monochromatic vegetal dyes. Each type of yarn and weave has a different reaction to the decoloration and dyeing process, yielding changeable hues and effects in an extensive variety of nuances, ranging from bold bright shades to natural and pastel tones. All processing stages are manually performed with precious yarns, consistently with the ancient art of embroidery.
