A papermaker's fabric is disclosed. The fabric is comprised of at least top and bottom machine direction yarn systems, each machine direction yarn system being formed of a plurality of yarns which defines a respective top or bottom plane of machine direction yarns. The yarns of the systems are vertically aligned and the top and bottom planes are parallel. A cross machine direction yarn system is interwoven with the machine direction yarn systems in a repeated pattern encompassing at least four adjacent top plane machine direction yarns, with the fabric top plane having an open area of at least 40% and the fabric having an air permeability of at least 900 CFM. The fabric as a substrate has special utility for an embossing fabric.
