How would you like to sit on your old jeans that have been rejuvenated back into your livingroom as a sofa?
A Japanese company is doing exactly this, you should note it costs about $400 for them to make you one, but I don’t see why not you can’t do this yourself on your spare time either.
This concept may seem to be a rather strange idea, after denim is not usually associated with furnishings, but in Japan the re-using of materials is a big thing and denim is coming through a good hard wearing and stylish covering for furniture.
