Zusammenfassung:	A method of making a belt-creped absorbent cellulosic sheet. A papermaking furnish is compactively dewatered to form a dewatered web. The dewatered web is applied to a translating transfer surface. The web is belt-creped from the transfer surface utilizing a polymeric creping belt having perforations. The web is creped from the transfer surface and redistributed on the creping belt to form a web including a plurality of fiber-enriched hollow domed regions protruding from an upper surface of the web, the hollow domed regions having sidewalls being formed along at least a leading edge of the web. Connecting regions form a network interconnecting the hollow domed regions. Transition areas include fibers that transition from the connecting regions into the hollow domed regions, by extending upwardly from the connecting regions into the sidewalls of the domed regions. The web is dried to produce the sheet.
