The simple little things we can do to change something in our home. And this one is super simple. You need a picture frame; new, old, recycled, homemade... whatever style you fancy.
One switch plate cover, electrical receptacle, thermostat or alarm panel ... basically, one of those ugly things that is stuck to your wall that you can't really do to much about moving without a permit or a professional.
Then do this. Quick and simple! Doesn't it look more interesting now? I think it would work really well if you had a switch plate or the likes framed such as above, incorporated it into a larger display of framed photos. The switch plate would become less immediately visible and tend to become part of the wall of artwork.
3M Command Picture Hanging Strips or something similar are ideal for attaching your frame to the wall. They hold really well and if you get tired of the frame or want to swap it out, you can easily take it down without damaging your walls.
I know, you're ready to get up and tour around your home to see what you can stick a frame around now aren't you.... I think I'll do one for my little guys room next :)
