I hung the woven grasscloth on the left about 20 (maybe more) years ago. About two years ago, the home had some water damage, and I used left over grasscloth to repaper the section around the air duct.
This is a sun room, and receives a lot of light. You can see how the color has changed over time, by comparing the paper that has been exposed to bright sunlight to the paper that was in storage for 20 years. Grasscloth is a natural product, and so has little resistance to fading.
