Pillow shams are decorative covers designed to enhance the appearance of pillows on a bed. Unlike standard pillowcases, shams often feature stylish designs, patterns, or textures, making them a popular choice for adding a touch of elegance to bedding. They typically have an opening in the back, allowing for easy insertion and removal of pillows. Shams come in various sizes to fit different pillow dimensions, such as standard, queen, and king. They are often used in conjunction with other bedding items, like duvet covers and bed skirts, to create a cohesive and visually appealing bedroom decor.
