This is the piece of fabric that creates a sheath or barrier between you and your pillow. Typically, a pillowcase has one opening on the short side of the fabric and extra fabric that will drape over a few inches, when placed over the pillow insert. The drape is sometimes generous and provides a decorative element to what is otherwise a largely functional piece.

Varieties of Bed Sheets: The most common are the flat and fitted sheets. Fitted sheets are designed to fit snugly over your mattress, often featuring elastic edges to secure them in place. Flat sheets, on the other hand, are laid over the fitted sheet and under blankets or duvets. They can also be used alone, especially in warmer climates for a lighter cover.
