Whether or not there's a lot of kitchen wall space left on view after the new cabinets and appliances are in place, you'll want your walls to support your decorating scheme. If your kitchen redo involves more decorating than remodeling, you'll be pleased at how much of an improvement new wall treatments can make.
Coordinate the wall treatment style and color with your cabinets, or, if your cabinets aren't being replaced, consider painting them to match the new wall color. Either way, you'll cool the clutter and create a more spacious, calming look, whatever your style.
