Painting-Stripes-on-Wall. I would add: After placing your tape, paint the wall color AGAIN where the new stripe colors are being applied BEFORE painting your stripes. Your stripe colors will be crisp and clean edged. Love the red dresser!
Pick a Pattern of Stripes for the Wall - Draw an arrangement of lines on the wall, using stripe heights or widths of 3 to 15 inches. You can choose to paint stripes of uniform widths (as seen here), or go for some visual variety.
