A canvas is usually made of cotton or linen but it can always be something else, especially you’re such a genius artist. Rome-based Russian artist Ekaterina Panikanova creates large-scale paintings using pages of books as canvas. Ironically, the series is called “Errata”, which is Latin for corrections of a book or article. The artist may not actually have committed an error with her paintings though. She essentially made her works more interesting and worth gazing at.
