My friend Janet, a graphic designer, has William Morris's Jasmine (1872) wallpaper in her front hall. Morris used the same paper in his study at Kelmscott House. It is incredibly welcoming. This pattern comes in a number of other colorways (and in fabric) which you can see here and below.
Note added later: The paint is Benjamin Moore Bavarian Cream.
