How to Paint a Perfect Chevron Wall Use a ruler to place small sticker dots, like ones you can buy at walmart that are meant for writing prices on, evenly spread out on a wall. Then use masking tape to go from one dot to the next in a zigzag shape. Do the same on the row above. You may have to cut off some excess tape -you can kind of see in the image where it makes a triangle where the tapes intersect. Follow the edges to cut off the excess and have smooth edges!
