We also found a beautiful diagram of the many ways you can use furoshiki to wrap bottles, boxes, books, and even watermelon.
We found this image, originally in PDF format, at the website of the Ministry of the Environment of the government of Japan. (There's a GIF version at Flickr.) We're thinking the diagram has decor potential as well. Some enterprising soul: print the above diagram on a square piece of cloth! Make a mint!
