Definition of Borders
A decorative strip of wallpaper which traditionally has been used as a chair rail or in combination with a chair rail. Because of the wide variety of designs and widths now available, borders are also used along ceiling lines, along the baseboard, around doors and windows, and in any manner that a trim could be used.
The use of borders can create charming atmosphere. If the room is relatively small, it is better to use top or bottom borders since it makes the room look longer.
