Shades often prove to be the preferred window treatment for the kitchen -- their straightforward look is free of pleats, swags, and puddles that require maintenance. When presented in a snappy print, window shades accomplish two goals: They inject a carefree mood, and they fit into the working nature of the kitchen.
Although shades that match the wall covering or another fabric print found in the room can work when properly designed, contrasting prints reserved just for the shades ensure the window's role as a focal point of the room.
The new print for the window shade must somehow relate to the other patterns in the room -- either by repeating the same color, or by picking up a color from the overall room palette, or by relating to the wall-covering pattern in terms of scale.
A small-print wallpaper is handsomely matched with a small-scale plaid shade, for example. Or dark burgundy or rose in the kitchen palette bears repeating, in a different pattern configuration, on the window shade.
