I agree, a quilt is composed of a top, batting and backing (sometimes doesn't even have to have batting). It can be a wall hanging or any size, doesn't have to be on a bed. I make quilts, but none are on my beds. They are hanging over the railing/banisters, on quilt racks and on my walls. Even big ones go on my walls as 'art'.
