A process is claimed for making a composite sheet (10) useful as topsheet with one or more openings (11) to receive fecal material useful for an absorbent article, said composite sheet (10) comprising a wrinkled, patterned elasticized region (12) that comprises a patterned first sheet (13) and an elastic material (15), said first sheet (13) being patterned with troughs (16), that are typically compacter, i.e. of higher density, prior to attachment to the elastic material (15). The troughs (16) are attached to the elastic material (15). The resulting composite sheet (10) has a uniform wrinkle pattern. Also claimed are specific absorbent articles. Also claimed are composite sheets (10) with a specific residual strain and peel force value.
