After newly wallpapering a kitchen, cut any leftover wallpaper to fit inside the cabinet face (Image 1). Apply the paper the same way as for the walls, by booking it, then applying it to the front of the cabinet.
Use trim that has been stained to match the cabinets to frame the four edges of the new wallpaper, adhering the trim with a glue gun (Image 2).
Paintable textured wallpaper is especially good for borders or chair rails. Some options:
Paint the textured paper with a metallic paint (copper or silver) to achieve a "metal tile roof" effect on ceilings.
For a decorative look to switchplate covers (Image 1), use the covers as a guide, add 2"-3" on each side and cut out a piece of wallpaper. Make sure that the selected piece of paper matches the design surrounding the outlet.
Center the switchplate cover on the paper and fold the paper over it as if you're wrapping a gift (Image 2), tucking in the edges.
