Cambodia-Artisans D'Angkor
Cambodian silk is exquisite, so the pleasant tour here will give you an appreciation of the labour (from the silk worms as well as the skilled people!) that go into every thread. The store here has a fine, reasonably upmarket collection of silk goods including purses, clothing and bolts of silk in brilliant colours
The quality of silk does not depend so much on the worm's origin ( Cambodia , Thailand , Vietnam , etc.), but more on the conditions (food, environment) in which it's raised.
