Abstract
As described herein, an extensible sheet material includes a first and a second zone that is separate from the first zone. The first zone exposes a first color or pattern when the extensible sheet material is stretched beyond a first percentage. The second zone exposes a second color or pattern when the extensible sheet material is stretched beyond a second percentage greater than the first percentage. Absorbent articles that include the extensible sheet material are capable of indicating to a wearer when the extensible sheet material has been stretched too little, too much, or just the right amount.
