You can buy any sized,
already-framed art. We got a piece of art that was very, very large and was on sale for 50% off. You can also get a framed cork board because those are super lightweight or a framed chalkboard. Just use anything that has a frame.
You can always find a color you already like, so you don’t have to paint that or you can just paint the frame like I did!
Since our frame was gray, we painted it black and added one finishing coat. Luckily the inside of our art was already black. If you do buy a piece of framed art, you will need to paint the entire picture that was inside the framed art black (or your color choice) to cover up the art.
