Throughdried tissue products such as facial tissue, bath tissue, and paper towels are made using a throughdrying fabric having from about 5 to about 300 machine direction impression knuckles per square inch (per 6.45 square centimeters) which are raised above the plane of the fabric. These impression knuckles create corresponding protrusions in the throughdried sheet which impart a significant amount of cross-machine direction stretch to the sheet. In addition, other properties such as bulk, absorbent capacity, absorbent rate and flexibility are also improved.
