I’d like to suggest that you include the Tinnery in Butare/Huye as an excellent place for tourists to visit. It is run by a lovely gentleman, Antoine Bizimana. Tourists can watch artisans working from start to finish – from melting the tin over an open fire to completing a beautiful tray or elephant figurine. Products are sold at the tinnery and through boutiques at various hotels (Novotel, Mille Collines). Here is the contact information:
Les ETAINS de l’Etainerie y’i Huye au Rwanda, 250 78 864 0923, firstname.lastname@example.org. The tinnery is located about 5 kilometers northwest of Butare on the Gikongoro-Cyangugu road.
