The surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments. Also, a fibrous structure having at least two plies is disclosed. One of the two plies has a density (measured at 95 g/in2) of less than about 0.60 g/cm3 and at least one embossed ply having a surface thereof. The surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments. ## Claims ### Claim 1 A fibrous structure comprising a pattern densified through air dried web having continuous high bulk zones and discrete high density zones disposed within said continuous high bulk zones and having a density (measured at 95 g/in2) of less than about 0.60 g/cm3 and an initial total wet tensile strength of less than about 78 g/cm (200 g/in), at least one embossed ply having a surface thereof, wherein said surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments, said line embossments comprising an asymmetrical embossing pattern. ### Claim 2 (depends on 1) The fibrous structure of claim 1 wherein said surface area comprises from 0.0 percent to about 1.2 percent dot embossments. ### Claim 3 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure is creped. ### Claim 4 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure is uncreped. ### Claim 5 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure is a paper web. ### Claim 6 (depends on 1) The fibrous structure of claim 1 wherein said surface has an irregular and asymmetrical embossing pattern disposed thereon. ### Claim 7 (depends on 1) The fibrous structure of claim 1 wherein said surface area has a ratio of line embossment area to dot embossment area greater than 1. ### Claim 8 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure is through-air-dried. ### Claim 9 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure comprises at least 2 plies. ### Claim 10 (depends on 1) The fibrous structure of claim 1 wherein said fibrous structure is a product selected from the group consisting of absorbent towels, facial tissue, and toilet tissue. ### Claim 11 A fibrous structure having at least two plies, one of said two plies comprising a pattern densified through air dried web having continuous high bulk zones and discrete high density zones disposed within said continuous high bulk zones and having a density (measured at 95 g/in2) of less than about 0.60 g/cm3 and an initial total wet tensile strength of less than about 78 g/cm (200 g/in), at least one embossed ply having a surface thereof, wherein said surface has a surface area comprising from about 10.0 percent to about 20.0 percent line embossments, and wherein said surface has a total embossment footprint area to total surface area ranging from about 5 percent to about 40 percent. ### Claim 12 (depends on 11) The fibrous structure of claim 11 wherein said surface area comprises from 0.0 percent to about 1.2 percent dot embossments. ### Claim 13 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure is uncreped. ### Claim 14 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure is uncreped. ### Claim 15 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure is a paper web. ### Claim 16 (depends on 11) The fibrous structure of claim 11 wherein said surface has an irregular and asymmetrical embossing pattern disposed thereon. ### Claim 17 (depends on 11) The fibrous structure of claim 11 wherein said surface area has a ratio of line embossment area to dot embossment area greater than 1. ### Claim 18 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure is through-air-dried. ### Claim 19 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure comprises at least 2 plies. ### Claim 20 (depends on 11) The fibrous structure of claim 11 wherein said fibrous structure is a product selected from the group consisting of absorbent towels, facial tissue, and toilet tissue.
