How to paint 3 stripes: 1. Sample colors and pick 3 that will complement each other. 2. Figure out the dimensions of the room and stripes width. My wall was 11 feet long. I chose 12 inch blue stripes, 6 inch yellow stripes, and 2 inch white stripes. 3. Paint the entire wall with the lightest color (the tape will cover this.) 4. Make your measurements, placing the tape exactly where you want it. 5. Seal the tape using a credit card. 6. Paint. 7. Remove tape about an hour later.
