Mixing and matching throw pillow patterns can be daunting, but there’s a Rule of Three for that, too. Designers suggest choosing three different patterns of varying sizes and making sure that each pattern has at least one of the colors in your throw pillow color story. To make this easy, choose a lead pattern, which has the largest design and all of the colors in the throw pillow color story. Then move on to the secondary pattern, which is a smaller design and might have only two of the colors. The third pattern is the most subtle throw pillow, usually in a solid color, and this is where designers tend to play with texture, like sequins, velvet, and faux fur.
