Mix Patterns Like a Pro

Odd numbers, especially the number three, just seem to make things work, whether you're combining colors or planting shrubs. Three is the minimum number of patterns you should use, and the key to successful mixing is to vary the scale, from small to large, of the patterns.

Pattern 1: Pick this pattern carefully because it will make the strongest statement in your room, says designer Shari Hiller from Room by Room. It should be a large-scale pattern.

Pattern 2: Select a very different pattern that's half the scale or size of the first pattern. If your first pattern is a large floral, the second pattern could be a plaid or geometric shape that has some of the same colors.

Pattern 3: The third pattern can be similar to either of the other patterns and use two or three of the colors in the other patterns. A smaller floral would work well, for instance, with a larger floral and a plaid.

Pattern 4 and more: Shari suggests that a fourth pattern, such as a tiny check or a printed texture in a small scale, could be used as a complementary pattern. Bedroom design by Turnstyle Interior Design

This can be a color you really like, a piece of fabric you've found, a favorite chair, painting or even a piece of clothing. Mother Nature, who rarely goes wrong with her color and pattern combos, is another good source of inspiration.

Don't mix pastels with primary colors, or muted with vibrant jewel tones, says designer Jayne Pelosi of Renaissance. A large floral, a smaller floral, a stripe and a check will work together if they are made from the same set of dyes in the same hue. Bedroom design by Sarah Richardson

Be aware that there's more to a fabric than simply its color, Jayne says. "All fabrics have a personality or a feel, as we say in the trade. Most people would identify damask, for example, as a formal fabric, even if they didn't know its rightful name! Conversely, most people would agree that muslin or gingham plaid are examples of casual, informal fabrics. These levels of formality absolutely come into play when you're mixing patterns."
