I think that burlap is something you either love or loathe. Either way, it's a much more interesting fiber than you'd think. And it can contemporary... not just country! It's "green" because it's made from jute, a very low-impact plant to grow. So it's renewable. Even compostable! Also, it’s pretty easy to get second-hand/used burlap, if you know where to look. Local coffee shops, especially ones that roast their own beans, tend to be rich with big, empty burlap sacks.
