In plain English: A quilt is a warm blanket made by stitching together many layers of fabric and filling to create a thick, cozy cover for your bed.

Usage: Use quilt to describe the specific type of warm bedding made by stitching three layers-top fabric, batting, and backing-together for insulation. Do not confuse this term with blanket or comforter, as quilts are defined by their stitched construction rather than just being a soft covering.
