A recent Design Sponge sneak peek and this Apartment Therapy House Tour reminded us of a great source for artwork — wrapping paper from from Cavallini & Co. Each sheet is sold for $4.50, so it's definitely artwork on a budget. We love the variety of options from vintage maps to images of food and of nature.
