If you have access to some old window covering books, usually there is one book devoted to "natural" type window blinds.  They contain samples using things like woven grass and bamboo.  Find one that suits the color and style you are after, and put gobs (LOTS) of glue down each of the far ends of the sample.  After about a day when it is dry, cut along the middle of that glue line and, presto, you have a "grass mat", "bamboo rug", or whatever else you want to call them :)  Here's a picture of a "jungle themed" room with a woven grass and bamboo throw carpet.
