Abstract: Provided are tissue webs and products that have a modest degree of surface texture, but are still soft. In certain instances the tissue products and webs may also have good sheet bulk and low stiffness. For example, the tissue products may have good softness, such as a TS7 value (measured using the EMTEC Tissue Softness Analyzer) less than 11.0, and a textured surface, such as an R2 value from about 11,000 to about 20,000 (measured using an OpTiSurf tester). The foregoing tissue products may have a sheet bulk greater than about 8.0 cc/g and a Stiffness Index less than about 15.0. In certain instances the tissue product and webs may be through-air dried and may be either creped or uncreped.
