So the measurement for a twin size quilt is 60x80. Is that the measurement for a quilt that is considered a "comforter"? or is that the size considered for a "blanket"? I want one for a comforter (bed spread) and one for the blanket on the bed and I dont' want the blanket to be larger than the comforter. I don't have a twin bed (yet) so I can't measure it!
