The days of the week in Oaxaca are told by market days. Sunday is Tlacolula, Friday is Ocotlán, Thursday is Zaachila, and Wednesday is Etla. These are the days when there is tiangis, meaning people from the area come to surround the permanent market and sell anything from turkey eggs to cell phone cases. Usually you can find stuff to do afterwards in each town (artisans or murals to visit for instance). But usually there isn’t a textile mill turned arts center and a paper factory on top of the hill. Etla is 30 minutes from Oaxaca, and well worth the colectivo ride.
