As I was told by the General Manager of Craft Link, Ms. Tran Tuyet Lan, not-for-profit organizations have to sell quality products in order to survive. Charity isn’t sustainable.
But Hanoi’s Hoa Sua School and Craft Link try. The customer gets quality food and handicrafts, respectively, in addition to the warm fuzzy feeling from contributing to a good social cause. It's an ideal – and apparently sustainable – combination.
