Abstract
A web product which is wound into a roll includes a web which is provided with at least one marker to aid a user dispensing the product. The marker extends tranversely across the inside surface of the web, and the web and marker are contrasting colors for visibility. A method of forming the web product includes the steps of providing a web, positioning a marker transversely across the web at a predetermined location, adhesively securing the marker to the web, and winding the web into a roll. The web and marker are contrasting colors so that the web can be unwound to expose the marker which signifies to a user that a predetermined portion of the length of the web has been unwound.
