Step 1: Plan Your Design
Measure your wall, and use its dimensions to plan your design. Work out the geometric plan on paper, noting all dimensions and planning the color scheme.
Step 2: Mark the Walls
Mark the walls with a pencil, measuring all dimensions.
Step 3: Apply Masking Tape
Put painter’s masking tape directly over the chalk lines. Pull the masking tape against the blade of a putty knife to make straight cuts at the corners and ends. Tape the geometric pattern on the entire wall. Make sure to press the edges of the tape firmly to the surface to prevent the paint from bleeding through underneath. A credit card comes in handy for this task.
Step 4: Begin Painting
Apply a few strokes of latex paint to one square (you can also use acrylic paint from an art store). Use a chamois cloth pressed into the painted area to move the color around and blend it in. The chamois cloth can be used wet or dry, depending on the effect you want to achieve. Work with one square of color at a time, as the paint dries rather quickly, adding a few more brushstrokes of paint as necessary and blending with the chamois. A few drops of dish detergent added to the paint will extend your working time. Pay special attention to the edges, making sure paint is applied all the way to the edge.
