1. A method of creping a cellulosic sheet, the method comprising:
(a) forming a nascent web from an aqueous papermaking furnish;
(b) depositing and creping the nascent web on a multilayer creping belt that includes (i) a first layer made from a polymeric material having a plurality of openings, and (ii) a second layer that is separate from and attached to a surface of the first layer, with the nascent web being deposited on the first layer; and
(c) applying a vacuum to the creping belt such that the nascent web is drawn into the plurality of openings, after the nascent web is deposited on the multilayer creping belt.
