I like natural materials but boy oh boy they must be on the endangered species list. And I can't see paying $$$ for...polyester!

But it seems I need to find a balance between cost and sort-of-natural materials. What do you think of the quality of these items? What should I look for while inspecting them to help me make a determination?
