The diamond shape of the harlequin pattern can add a touch of character to any room of your home. Living rooms, dining rooms and bedrooms are ideal locations for this unique pattern. An accent wall with a harlequin pattern creates an interesting visual when you walk into the room. Your personal preference will determine what size diamond shape you use to create the pattern. The most common diamond shape in a harlequin pattern is twice as tall as it is wide. There is no set size for the pattern.
Paint the desired wall for the harlequin pattern with your base paint color.
Measure the wall's height and width. Determine the size of the harlequin pattern in order to fit an even number of diamonds across the wall. For example, if your wall is 8 feet tall and 12 feet wide, you might want a diamond shape 12 inches tall and 6 inches wide. This would create eight diamonds in each vertical row and 24 in each horizontal row. Mark the wall every 12 inches vertically and every 6 inches horizontally. Connect the marks diagonally with one another to create the diamond shapes.
Set the size of the diamonds first if you do not need an even number of diamonds, and mark the wall to those measurements. Alternatively, make a diamond-shaped template. Place the template in the top center of the wall to begin, and make marks on the wall at its points repeatedly from top to bottom and side to side on the wall. Use a measuring tape and straightedge to make straight diagonal lines at regular intervals to create a grid.
Cover any edges of the room that you don't want painted with painter's tape, such as ceiling and trim.
Tape along the outside edge of every other diamond with painter's tape. Paint these diamonds with contrasting paint to create the harlequin pattern. When dry, tape around the alternate diamonds and paint these with the same contrasting paint.
Allow the paint to dry 24 hours. Remove the painter's tape.
