Often people are worried about mixing patterns or using a pattern to much. Not so! Many traditional decors use a pattern or two extensively in a room. As in the picture shown, use one pattern on the walls (yes, you can put fabric on the walls - covers imperfections beautifully), in the drapes, in bed coverings, furniture, accents (pillows, shades, and more). Of course, if you use one pattern so predominantly, make sure it's light, airy pattern or the effect may be too heavy. That's why toile (pictured) works so well and is making such a comeback.
You may also take two patterns that complement each other (one is usually large, the other small in the same colors). Use them throughout a room in the furnishing, accents, window treatments, and more. For example, in a bedroom, you can use two patterns between the drapes, bed cover, dust ruffle, accent chairs, table covering, headboard, and more.
The effect will be luxurious, coordinated, and very designer-like. In other words, it will look like you spent lots of money hiring a decorator when all you did was use one of their favorite tricks!
