Paint the wall a solid color. This will be your background color.
Select an acrylic paint color that contrasts nicely with the background color.
Prepare and tint the glaze with the acrylic paint you have chosen to create your desired glaze color.
Use a yardstick and a light-colored pencil or piece of chalk to measure and mark off even intervals across the length of the top edge of the wall.
Measure and mark off the same intervals across the bottom edge of the wall.
Using blue painter's tape, tape off vertical strips from each mark at the top of the wall to the corresponding mark at the bottom of the wall. Your wall will be covered with evenly spaced, parallel strips of tape.
Using a small roller, apply glaze to the exposed surface of the wall.
After the glaze dries, carefully remove the tape.
