A method for making a multiply fibrous structure. The method comprising the steps of: depositing a slurry of pulp fibers onto a Fourdrinier wire running at a first velocity V1; transferring the web from the Fourdrinier wire to at least a first molding member moving at a second velocity, V2, slower than the first velocity, V1. The molding member comprises a substantially continuous relatively low density network at least partially defining a plurality of relatively high density, irregularly shaped, discrete elements situated in an irregular pattern. The embryonic web is partially dried, adhered to a Yankee dryer surface, creped from Yankee dryer and reeled at a velocity, V4, that is faster than that (V3) of the Yankee dryer.
