A tie has many usable parts.  There is a piece of fabric at least 3" wide and 45" - 50" long, 2 finished ends that can be used as prairie points, usually a label that can be used as an embellishment, and sometimes an additional lining that can be pieced with others to line small items.  A demo attendee suggested using the interfacing to cut headers (stiffener) for armhole seams.
