Paint the wall with a base color and let it dry. Use a yardstick to determine the width and length for your chevron stripes.
Decide where you want the chevron’s peak at the top of the wall; mark this as point A. Measure down the width of a stripe with a ruler and mark point B; use the level to ensure the marks are vertically aligned. Measure the length of a stripe from the peak to the edge of the wall and mark point C. From that mark, measure down the width of a stripe to mark point D. Use painter’s tape to connect points A and C, and points B and D. Cut the tape with a crafts knife to create sharp corners.
Tip: Mark the wall from the top of the wall to the bottom for one side of the chevron, then move to the other side.
When the paint is dry, slowly pull off the tape. Use a small crafts brush to make touch-ups.
