during my visit to chettinad, i went to a tile factory at athangudi, close to kannadukathan village.. its a common enough thing to do. and there are sufficient of them, and all tourist-friendly. that’s not a compliment. but in a village known for tiles and their aesthetics, they charge to watch them at their art! but, anyway i was there. and people had told me about it. and i had to do it.
