Abstract
The present invention is a new elongate single-ply paper napkin that achieves the necessary absorbency, strength, hand feel and softness for commercial use but which is less expensive than traditional napkin products. More particularly, the invention is a single-ply napkin that contains folds running only in the transverse direction of the product, i.e. perpendicular to the length of the napkin.
