Every year I change my A2 art folder, because buying a new one is too expensive. This year I decided to change from black to white in order to identify my portfolio quicker among all the other black ones. Certainly almost no one will have it in white monochrome. It only took some patience to paint it and two spray cans from Leroy Merlin (10€). My folder looks new and has a great visual impact. Recycle your school material, you'll not regret it!
