1. A process for making a multi-ply fibrous structure-containing article, the process comprising the steps of:
a. passing a fibrous structure ply through a nip formed by two rolls at least one of the two rolls comprising a plurality of protuberances such that the resulting multi-ply fibrous structure-containing article exhibits a Core Height Value of greater than 0.60 mm as measured according to the Surface Texture Analysis Test Method to form an textured fibrous structure ply; and
b. bonding the textured fibrous structure ply with at least one other fibrous structure ply by a water-resistant bond to form a multi-ply fibrous structure-containing article, wherein a void volume exists between the bonded textured fibrous structure ply and the at least one other fibrous structure ply of the multi-ply fibrous structure-containing article.
