Rugs produced in villages are often produced in individual homes, but at least partly commissioned and supervised by guilds or manufacturers. Home production may not require full-time labour, but could be performed when time allows, besides other household tasks. Village carpets as essential household items were part of a tradition that was at times influenced by, but essentially distinct from the invented designs of the workshop production. Frequently, mosques had acquired rural carpets as charitable gifts, which provided material for studies. Rural carpets rarely include cotton for warps and wefts, and almost never silk, as these materials had to be purchased on the market by the individual weaver.
