Floor-to-ceiling navy paint stripes, framed with white molding, wake up bland walls. Outline each stripe with painter's tape (the stripe here is 2 feet wide). Cover edges with molding. Flank a fireplace, TV or any other focal point for a shot of color that's not a major commitment.
For inexpensive art, frame small sections of bold-hued fabrics. We picked two patterns with stylized birds to create a unified display.
Add easy-to-change color to walls by covering prestretched painter's canvases (from crafts or art stores) with fabric. Secure with a staple gun. One solid panel grounds the geometric prints.
Paint only the bottoms of legs on a side table (as if you're giving it a sassy pair of shoes).
To quickly brighten a plain pillow, wrap patterned fabric around the middle. Secure with safety pins.
A headboard gains colorful style with a striped woven rug draped over it. Secure with clip-on drapery rings and ribbon.
Glued-on fabric or wallpaper gives a plastic pull-down shade an arty update. Paint just the window trim to frame the shade.
Remake an ottoman with a flat-weave rug (or fabric). Fold the rug under the ottoman, like you're wrapping a package, and secure with a staple gun.
Dark coral paint on a tall canvas and light coral on a short one add up to one great piece of art. Layer canvases; attach from back with screws.
