A 17-year-old Canadian student, Kara Koskowich recently decided to do something creative for her high school graduation. She opted to make her own grad dress, and she used her old math homework as the material. The math homework dress was created with around 75 pieces of paper. She cut, sewed and glued pieces of paper — including coloured Post-its for detail — to complete the dress. She started making the dress in March but only finished just before her graduation. Her best friend joined in the creative task and also made her own dress, using recycled plastic bags.
