This topic may conjure up images of country decorating, but that's not necessarily so. A friend of mine has a lovely wall quilt in her family room. With simple squares of various metallic fabrics, it's contemporary and traditional all at once. And it gives a very warm, rich look to her room as the colors coordinate beautifully with her other artwork and furnishings.
So you can go for a traditional quilt pattern in a smaller size for a wall, or go beyond your imagination.
