Bedroom headboards, especially long solid ones with lower ceilings above them, are a bit tricky when it comes to artwork. Everyone wants to put some sort of a painting above them, but a large piece tends to "argue" with the actual headboard. Throw a splash of color onto that wall by painting several canvases with the same subject. Then, add a twist by coloring each one a bit differently then the other ones; large, bold shapes work especially well for contemporary styles. Remember to keep some sort of continuation in all three; in this particular group I made sure that the backgrounds are almost the same. This creates a feeling of consistency; the three become a single piece of art. I had fun with this project, hope to see what you came up with. Have fun!
