Bedspreads are primarily large and decorative and are designed to cover the entire bed, while a quilt is generally a little smaller and perhaps a bit thicker providing both decorative and functional warmth.
A quilt is traditionally made up of two layers of fabric with a sandwich of batting in the middle although some of our quilts are constructed using a different technique with strings rather than batting. Our larger quilts can easily be used as a bedspread on a smaller bed.
