Other methods such as wet molding, forming on three-dimensional forming fabrics, drying on nonwoven substrates, rush transfer onto embossing fabrics, embossing, stamping, and so forth may be used to create useful three-dimensional structures. The basesheet may be formed as a unitary multilayer structure in which various plies are well bonded and intimately connected to each other. Unitary multilayer basesheets may be formed using layered or stratified headboxes in which two or more furnishes are provided into separate chambers of a headbox, or they may be formed using separate headboxes by couching the wet webs together prior to drying in order to allow extensive hydrogen bonding to develop between the plies during drying, or they may be formed during air-laying by varying the composition of the fibers and additives imparted to web. Multilayer sheets allow better control of physical properties by tailoring the material composition of each layer. For example, a unitary multilayer basesheet useful for the present invention would have an upper layer, corresponding to the upper surface of the basesheet, and at least one remaining layer below said upper layer and integrally attached thereto, preferably through hydrogen bonds formed between cellulosic fibers during drying, wherein said upper layer differs from at least one remaining layer of the basesheet in terms of material composition. The difference in material composition may be due to differences in fiber species (for example, percentage of hardwood versus softwood); fiber length; fiber yield; fiber treatment with processes which change fiber morphology or chemistry such as mechanical refining, fiber fractionation, dispersing to impart curl, steam explosion, enzymatic treatment, chemical crosslinking, ozonation, bleaching, lumen loading with fillers or other chemical agents, supercritical fluid treatment, including supercritical fluid extraction of agents in the fiber or supercritical fluid deposition of solutes on and into the cell wall, and the like. The difference in material composition between the upper layer and at least one other layer in the basesheet also may be due to differences in added chemicals, including the type, nature, or dosage of added chemicals. The chemicals added differentially to at least one layer of the web may include debonding agents, anti-bacterial agents
