Fake markets have tons of this stuff, might not be exact replicas - you will have to bring a digital picture of exactly what you're looking for. I would be hesitant to take a picture to the fabric markets and try to get something "authentic" made.... might raise a few eyebrows there.
When lying, dont be afraid of contradicting yourself later. Lies are not for making people actually believe, they are just for evading a temporarily awkward situation.
