These vegetable dyed carpets appeared in the 1990's, as Afghanis have began weaving a new type of carpet, using vegetable dyes on hand-spun wool. These carpets usually have golden or wheat coloured fields, though some pieces utilize other colours in the fields. They are generally based on antique patterns from Persian carpets. They have become known in the trade as "Chobi" (translates "wood"). Afghan weavers  use the fine  wool from the Ghazni mountain range west of Kabul.
