You can create a great wall in a matter of minutes: Draw geometrical figures and paint them with bright colors. The results will be amazing:

Or paint circles (a cookie cutter makes an excellent template) randoml on your wall and then glue buttons to the center of the circles. Silver circles with gold buttons add a formal touch, while funky buttons over bright circles of color will give that wall spunk and personality. For an added touch buy polka dot shams and add buttons. The end result will be an unusual and buttoned-up room.
