I read a book "Secrets of Spinning, Weaving, and Knitting in the Peruvian Highlands", which is available in many libraries in California, US. From this book I knew the textile center and decided to visit it once arrived in Cusco.
The live demo here is pretty interesting and the goods sold here are of high quality. Yes, it's more expensive than elsewhere and pay attention to the price tag as it's in US dollar, but you can still find something, for example, a 100% alpaca wool long scarf, with weaver's information, at $45, seems good to me; its feel is so soft and warm and the style is beautiful. You can clearly tell the difference between it and the things sold in the market at the other side of the street.
