If you want to see some beautiful ancient textiles and even find some incredible older pieces to buy, stop in and meet the Olivera sons or, if lucky, even get a moment with the expert, the mother. These are the people who know about the Quechua and Aymara weaving of highland Peru. Back in the days, their shop was across the street from the railway station for trains to Machu Picchu, but they have been in this location on the Plaza de Armas for the last 30 years or so. Pablo and Gregorio are the brothers you are likely to find in the store these days, but it was Manuel who worked by his mother's side when I first found them 40 years ago; all have a degree of expertise that makes their conversations invaluable. Buy, if you can, since the items they have for sale are irreplaceable! Let them tell you about the different regions and their symbols, and be open to learning about a marvelous art form that is still alive and well, even though there are few of the old pieces left.
