Where can you buy a dream catcher?

Being of Native American descent I would not advise you to purchse one which is not authentic Native American. Dream catchers were first made by the Ojibway tribe, know to most Americans as the Chippewa Indians. Ojibway people would tie sinew strands in a web around a small round or tear-shaped frame--in a somewhat similar pattern to how they tied webbing for their snowshoes--and hang this "dream-catcher" as a charm to protect sleeping children from nightmares. The legend is that the bad dreams will get caught in the web. Traditionally Native American dreamcatchers are small (only a few inches across) and made of bent wood and sinew string with a feather hanging from the netting. Today these dream catchers have become just a pretty thing to decorate living rooms or car Windows if this is the case you can find them at your local flea market and such, but if an authentic one is wated for traditional use they can be acquired on reservations throughout the country.
