Finding raw material for his rug would not have been much of a worry for Puerto Rican artist Jesus Bubu Negron, who made use of used cigarette butts to create a rug. He commissioned street cleaners to collect these butts, and well, cigarette butts are everywhere so the collection is unlikely to have posed any major problems.
Creating a carpet from those cigarette butts, though would fall into an entirely different league. The artist made use of the paper on the cigarette butts to create an intricate pattern that make the rug look so remarkably similar to woven textile pattern on carpets.
Yellow and white papers are used with great expertise to create the carpet that would pass off as a conventional one, until given a closer look. Artist Negron displayed his work at the Sharjah Biennale, documenting the street cleaners at work and helpers fabricating the carpet.
