I've seen some amazing quilts, they are the tapestries of our day.

Light sconces above each painting is one way to decorate but I found another way to illuminate wall art from 10 to 30 feet away by putting a light behind a crystal ball (12 inches or more) that acts like a lens and can focus a beam on large or small works. Works with lasar projectors too. Putting a small crystal ball (6 inches) in a gold fish bowl filled with water makes an unusual conversation piece.
Other unusual effects can be done with mirrors and sunlight that can project a reflected image on picture windows (old movie technology).
