Paint the walls a soft shade of a contemporary neutral color. Khaki, warm ochre, sage or a gray-blue provide several good choices. Depending on the event taking place in the hall, walls may be used as a backdrop for photographs, making a neutral color desirable.
Paint a broad horizontal stripe at least 12 inches in height around the center of the entire room. Position the stripe about one-third of the height of the wall. Use a lighter shade of the wall color to contrast with the wall color. With a darker color, use an artist's brush and a craft paint to illustrate biblical quotations inside the stripe.
Display a decorative bulletin board on a wall where announcements, articles and memos can be posted. Staple a seasonal garland to the edges to embellish the board.
Hang a chalkboard on the wall where menus or an important event can be noted. Frame the board in a decorative frame painted to coordinate with your wall color.
Mat and frame several pieces of art created by kids in Sunday school. Display them as a grouping to accent one wall.
