This is a very affordable means to hide ugly wall fixtures without causing any damage to the wall itself. Ideal if you are renting a place and on a budget or just like playing with cardboard.

Step 1: Gather Materials

You will need:
a piece of cardboard in decent condition
a photograph or decorative paper
measuring tape
T-square, triangle or something to help you draw a straight line
double-sided tape
good razor
straight edge for cutting
cutting surface
a level (optional)
4 pushpins

Step 2: Identify Offending Fixture

Ugly sconces are a bummer. Especially if there is little you can do about it.

Step 3: Take Measurements

Record the width, depth and height of the fixture.

Step 4: Measure Twice, Cut Once

Before you start slicing and dicing figure out how you are going to cut the cardboard.
To get the overall width that the piece will need to be do this equation:
(sconce width + 2") + (2 x sconce depth + 4")
The height of the cardboard piece should be at least as tall as the light fixture.

If you are using a cardboard box cut along the edges to get a long, flat piece. Using your tape measure and T-square or triangle map out the dimensions with pencil. Try to keep it straight.
Using your cutting edge (preferably metal), razor and cutting surface slice along the pencil marks getting rid of excess cardboard.

Step 5: Making the Sides

With the correct side facing up measure 1" in on the sides and mark with pencil. Create a crease along that 1" border by holding the straight edge in place at the pencil marks and fold the cardboard over it.
From the new crease measure the needed depth (sconce depth + 2") and repeat folding technique.
The sides are done!

Step 6: Making the Face

Here is where your photo or decorative paper come in. Measure your picture. Subtract at least 1" from the height and width.
On the reverse side of the cardboard map out the new height and width area with pencil. Try to keep it centered (unless you are making something asymmetrical).
Using a straight edge and razor cut out the center.
Apply double-sided tape around the opening.
Flip the cardboard piece over and center the picture in the cut out area. Press down firmly onto picture.

Step 7: Attaching to the Wall

This is easier with two people but not necessary.
Position the sconce cover in front of the light fixture by holding it. Keeping the side at a 90Âº angle to the front attach one of the side flaps to the wall with push pins. Using a level attach the other side the same way.

Step 8: Enjoy!

I love these things. There are so many possible variations and I really like how clean they look. Please see the next and last slide for design option 2.

Step 9: Design Option 2

I made this one first without recording the steps. The difference is that I cut out a traced silhouette and applied paper to the inside.
I look forward to seeing other versions.
