The perfect roller would hold a roomful of paint, leave the right amount of texture, wouldn't spray or fuzz, and would be easy to clean. Until somebody invents the ideal one, follow these tips to choose the right roller. "The longer the nap, the more paint the roller will hold, but it will also create more texture." says Dixon. "A 1/2-inch nap lamb's-wool roller holds plenty of paint without too much texture," says Dixon. "Less expensive rollers can work," says Span. "Just wash them first in dishwashing liquid to remove any stray fibers." Most of the pros we spoke with prefer 9-inch rollers over 18-inch models -- they are lighter, cheaper, and easier to use. Despite these shortcomings, Maceyunas swears by the wider roller. "The roller can do a whole wall in a few up and down strokes instead of in several dozen W and M strokes," he says.

While a homeowner might leave a bit of paint on the window pane, a dedicated interior painter for hire will make sure that these small details are handled properly, because a perfect job is the best calling card.
