What do you mean by design? Build it? Is it existing? What's it made of? Need more info.
Hi Karolyn: You can get several frames from the dollar store and put pictures in them from magazines. You can change them out often, and it's pretty inexpensive. Or, you can hang a tapestry on it. Good luck
You could nail up some barnwood on the wall, some huge decals that carry on the theme of the room (amazon has hundreds), a big cloth would add detail and function, a gallery of pictures. Sort of depends on what room specifically.
I love a gallery wall. With pictures, mirrors, frames, old windows etc...
