Awamaki
If you've made it to the Sacred Valley, you've likely seen your share of woven garments. But it's worth swinging by this fair-trade shop just down the road from the Plaza de Armas on the way to the ruins. All the extremely high-quality goods are produced as part of the Awamaki weaving project, which supports a cooperative of Quechua women from the Patacancha Valley. The organization also has a variety of cultural tours and other offerings, including homestays and weaving courses, all of which you can find out about at the shop.
