Once flowers have already bloomed, they are usually thrown away. But in order to enjoy them longer and create something of value from the waste, Zoubida Tulkens made wallpaper from rose petals. She collected rejected roses from flower growers, removed the petals, and made each one smooth using a flat-iron. Using a natural glue, Tulkens stuck the petals on wallpaper. Each sheet of wallpaper has it’s own pattern, and four sheets together create a larger pattern.
