I would do two smaller pieces on that wall, hung side by side. One covering the box and one just to the right of it.

hang a picture stretched on wooden frame, like a canvas.

Mirror maybe?

You could frame it! Maybe with some sort of gilt, ornate frame. Then you have access to it as well in case you need to flip the switch. : D

The green thing? I parsed it as art, probably because it matches the bedding so well.

I would think covering it would depend on how often you blow a fuse...at my house that's a pretty regular occurence :)

You could put another picture right on top of it that was the same size as the fuse box.

paint it to match the wall.

or, get some nice big lamps for those bedside tables and don't worry about it.

Maybe you could hang framed pictures on both walls intersecting in the corner, as was recently shown on one of the AT sites?

Put a pair of pictures on that wall and a pair of pictures (same size, same proportions) over the other dresser. Lo! Symmetry!

I have a fuse box in my hallway and I bought really cute magnets and use it was a bulletin board covered with postcards, pictures and my to-do list.

Thanks for the suggestions! Wow Leah I think your idea will work great- especially since I am on a budget and can't afford a lot of new artwork.
