Giving a picture frame an aged look is a cinch! Start by painting an unfinished-wood frame with two coats of craft paint in contrasting colors like red and teal, letting the paint dry in between. Then sand the frame here and there to let the undercoat and the wood show through. For an artsy touch, glue a vintage-style card catalog number in the bottom center. Make a whole set of frames in different sizes and colors, then hang them on the wall for a modern take on a classic photo grouping!
