How to Decorate Large High Walls

Measure the space over an architectural feature, such as a fireplace or window. Measure the height of the wall from about two feet from the ceiling or beginning of a peak, to about a foot above the window, door or mantle. Measure the width of the window or mantle also, knowing that you will center the decorative piece on the wall.

Purchase metal sheeting that will fulfill the measurement requirements of the wall. Many sheets are an average of 26-inches wide by 12 feet long, so a purchase of somewhere between four and eight sheets will be needed depending on your exact measurements.

Lay out the metal sheeting in a garage, driveway or other protected floor surface. Clean the surface of the metal and degrease if necessary. Allow to dry completely.

Brush iron paint onto one side of the metal sheets with a large sponge brush. Cover the entire front or display surface of the sheeting, including any crevices and creases. Allow drying.

Arrange metal sheets on the ground in the direction you are going to hang them onto the wall.

Use a permanent marker to number each sheet on the back of the metal. Create a diagram of the numbered panels and the way they are to be hung.

Pour rust antiquing solution over the metal sheets from top to bottom, in the direction they will hang. Allow the solution to drip, pool and cover the iron in a spontaneous way.

Allow 24 hours for the rusting solution to affect the iron paint. Apply additional rusting solution to the metal sheets to increase the color or effect as necessary.

Spray or paint a clear shellac finish over the rusted metal to seal and protect it from dust and chipping.

Find the center of the wall or the center of the architectural feature by measuring the wall or length of the mantle or doorframe. Divide that number in half to find the center.

Determine the center point of your art piece by referring to your diagram and dividing the width of your piece in half. Note what numbered panel will be installed at that center point.

Starting at the bottom-center of the area, install the designated center metal sheet on the wall with metal screws. Attach along the edge every three feet to ensure a secure installation.

Continue hanging the art piece on the wall following your diagram. The piece should cover the entire central surface of the large, high wall.
