Wallpaper border with twig vines on neutral background?

The perfect border I'm searching for, (6-7") will "pull" together the room. This room has been painted a light sandstone green (sand in the paint). Shutters on bottom half of windows have gr cloth inserts, bamboo shades at top, and cedar shake shingle canopy placed over top on outside of frame. I like to decorate using "earthy & simple" objects.
