Watch outTouts in these lanes offer to take you to a 'government silk emporium' or a family workshop and take a large commission. There is no government silk emporium in the lanes.
Tip: Go with a recommendation from your hotel rather than a street guide. Genuine handloom Banarasi carries a Silk Mark and a Geographical Indication tag.
Watch outPowerloom and viscose pieces are sold as handloom silk at handloom prices — the difference is many multiples. On real zari brocade the reverse shows floating threads; printed imitation does not.
