To generate bulk, cross directional tensile, absorbency, and softness in a sheet of tissue, napkin or paper towel, a fabric is often constructed to exhibit plane differences between strands on the top surface. However, single layer fabric designs do not allow for optimized balance between support and stability. The present invention relates to a multi-layer tissue forming fabric, constructed so that the top forming surface has topographical differences measured as a plane difference between at least two top weft yarns. The plane difference must be greater than zero. Using at least two different diameter, size, or shape weft yarns positioned at the same contour in the forming surface creates this plane difference and defines pocket areas in the forming surface of the tissue forming fabric. The pocket areas act to generate bulk, cross directional tensile, absorbency, and softness in a formed sheet of paper.
