Decorative pillows can turn a room from austere to cozy and inviting and can express your personal sense of style. Here you’ll find decorative throw pillows in a wide variety of shapes, sizes, colors and materials, making it easy to find ones that compliment your home. If there are children in your household, you’ll want pillows that can be cleaned easily. Polyester throw pillows are usually machine washable, making them a good choice. If you have pets, look for smooth-surfaced pillows, which can be easily cleaned with a lint brush. The most common sizes for decorative pillows are between 12 and 30 inches. Square and rectangular pillows are measured by the length and width, while circular pillows are measured by their diameter. Pillows appear about an inch smaller than their stated size, so add an inch to account for the pillow’s stuffing.
