American Apparel came up with a crafty new project for Earth Day called Creative Reuse. Instead of tossing away leftover fabric, AA uses it to design more styles at the same time as the originally intended garment is being manufactured. This cuts down waste both in terms of time and materials. The style is called ‘Mixed Marker’ – a marker being the guide that workers and machines use to cut the fabric. Things like underwear, bathing suits, and even more complicated garments like tank tops or pants can be made this way.
