Maya*made got some coffee bean sacks from her local coffee roaster (for FREE! they have a ton of these and were glad to get rid of them. Score! Do the same at your local roaster!) and covered a garage saled bulletin board with it for some instant coffeehouse chic in her office.
Instructions at the maya*made blog.
