Here's an example of a shaker tape seat done in one color.  Shaker tape can be done on any chair that could take a fiber or natural rush seat as well, but I do not recommend it.  The tape is cloth; and as such is much more susceptible to staining, and the color(s) fade substantially.  Also, the more it is sat upon, the material stretches and begins to sag; making for a very uncomfortable perch.  The "tape" comes in a couple different widths and several colors, and I require you to purchase the material needed yourselves (I can link you to a good source if need be).
