I recently had a conversation about how re-purposed/ recycled materials were becoming more sophisticated looking- less used. This is a very good thing. For something that is wholly re-purposed to read first as beautiful, then as eco-friendly is an acheivement well worth the undertaking.
These gorgeous rugs by Golran, called Carpet Reloaded are a stunning example. They are well-worn rugs whose color has been stripped (both by actual wear, and then by process of the designers) and then re-dyed in some cases. Others are simply patchworked.
