Tiffany Threadgould is living a DIY life. The Chief Design Junkie at TerraCycle, an international waste management company headquartered in Trenton, New Jersey, grew up recycling. So when it came time to furnish her post-college New York City apartment on the cheap, upcycling was a natural next step. “I was just taking cast offs from the street and making things from found objects,” Threadgould says. “It wasn’t really environmental — it was more about cost.”
