The first thing you need to do is pick your paint colors. One will be your basecoat, and the other will be the stripe color. You can do a tone-on-tone (same color, different sheens), you can do a monochromatic effect (same color, different shades), or you can go bold with two completely different colors.
STEP 1: Paint your base coat and allow this to dry completely. Painting stripes is not a one-day project, unless your base coat is already done. It is best to use the lighter color for the base coat and allow to dry overnight.
