Decide how many colors you want to use. Then figure out how tall your wall is and divide the height by the number of colors you're using. That will tell you how tall each section needs to be.
STEP 1
Once you know how tall each section needs to be, divide up your wall. You can start by making a few small marks with a pencil or just go right ahead with the painter's tape.
STEP 2
Start painting the sections in each of their respective colors. Remember, the tape is just there to help you see where each color section should start and end. You do not (and should not) paint right to the tape like you normally would!
STEP 3
Peel off the strips of painters tape!
STEP 4
With one paint brush, paint a few strokes of one color, covering about half of the white "gap" that you've left between the two colors. Use another paint brush to brush the other color right above that, so they meet (or almost meet) in the middle.
STEP 5
Immediately use a third brush to blend the two wet colors together, making long strokes back and forth over them. More is more here, continue making stroke after stroke to thoroughly blend the two colors together.
