Frame illustrations from a book or magazine. Art magazines and vintage books are great sources of frameworthy illustrations — just cut pages out neatly and pop them into any blank frame you have lying around. Once I framed a whole series of '70s surfing photos from a feature in The Surfer's Journal (a particularly artsy surfing mag) for a cool retro take on the beach theme. Look through your stacks with a fresh eye; you never know what you may find.
