We claim: 1. A method of making a paper napkin comprising: (a) providing a single-ply paper web having a machine direction and a cross machine direction, wherein a longitudinal dimension is in the machine direction and a transverse dimension is in the cross-machine direction, and wherein the longitudinal dimension is at least about two times the transverse dimension; (b) optionally orienting the web for longitudinal folding in the machine direction; and (c) folding one transverse free edge of the single-ply paper web toward the other transverse free edge to create two panels in the single-ply paper web; wherein the napkin contains no longitudinal fold and at least one transverse fold. 2. The method according to claim 1, wherein the two panels have approximately equal areas. 3. The method according to claim 1, wherein the single-ply paper web provided has a longitudinal dimension ranging from about 9½ inches to about 13½ inches, and a basis weight of at least about 13 lbs/3000 sq ft ream. 4. The method according to claim 3, wherein the two panels have approximately equal areas. 5. A method of making a paper napkin comprising: (a) providing a single-ply paper web having a machine direction and a cross machine direction, wherein a longitudinal dimension is in the machine direction and a transverse dimension is in the cross-machine direction, and wherein the longitudinal dimension is at least about two times the transverse dimension; (b) optionally orienting the web for longitudinal folding in the machine direction; (c) first folding one transverse free edge of the single-ply paper web toward the other transverse free edge to create a transverse fold line dividing the longitudinal dimension of the single-ply paper web, and (d) subsequently folding the first transverse fold line toward the transverse free edge to create at least one additional transverse fold line on the single-ply paper web; wherein the napkin contains no longitudinal fold and at least two transverse folds. 6. The method according to claim 5, wherein three panels are formed on the single-ply paper web. 7. The method according to clam 5, wherein four panels are formed on the single-ply paper web. 8. The method according to claim 5, wherein the single-ply paper web provided has a longitudinal dimension ranging from about 11½ inches to about 17½ inches, and a basis weight of at least about 16 lbs/3000 sq ft ream. 9. The method according to claim 6, wherein the two panels adjacent to the first transverse fold line are approximately equal in area. 10. The method according to claim 6, wherein the two panels adjacent to the transverse free edges of the single-ply web are approximately equal in area. 11. The method according to claim 7, wherein the four panels formed on the single-ply paper web are approximately equal in area.
