In all my years of travel, I can think of 4 souveirs, I wish I'd bought.
You see that stuff at garage sales.
I've never seen any of this stuff (that I can see from the chair I'm sitting in) at a garage sale:
Good Burmese lacquerware
Betel nut boxes, etc. from Laos, Burma, and Cambodia
Old, well-used "hill-tribe" basketry
Tara, Buddha, and other images from Nepal, Burma, etc.
Old ritual knives, bells, cymbals, and so on from Tibet and Nepal
Thangkas (one very nice one in this room)
Silk curtains/sarongs from Laos and Cambodia (hanging on carved sandlewood)
Beautiful rock from the hillside overlooking the crematory fires at a river in Nepal
(Not buying much these days, though.)
Yeah, there is some seriously good stuff in here. I'm so glad I brought it home. And I'm so glad I can have good coffee every morning, even in coffee wastelands like HK and Cambodia. And gladder still that I don't need to buy fake antibiotics, etc. if I get sick in Asia.
