I wanted to share this picture of a sofa with accessory pillows. I love mixing patterns. I think it makes a space look more interesting than just using a solid and a pattern. You have to be careful when mixing patterns. A rule of thumb to follow is to make sure your patterns have a common color. In this example, blue is the common color. Pair a smaller pattern with a bold pattern that have common colors. All of the patterns in this picture are different, but it works. If this is too much pattern for you, then feel free to use a solid color. You could place a sold blue pillow on each end of this sofa and add the patterned pillows in front.
