What is sham bedding?

A sham in bedding is used as a protective and decorative cover for a pillow, which keeps unsightly stains, dust, and debris out of sight. Additionally, shams are decorative on the front and back, usually with a pattern or design that matches a duvet for a bedroom set. Pillow can be covered with a sham and arranged at the head of a bed so that a bedroom has a delightful and aesthetically pleasing presentation. When it is time to retire for bed, the shams can be removed from the pillows.
