The french fold is a nice simple napkin fold that requires no special skills or tools.
1
Lay the napkin face down in front of you.
2
Fold the napkin in half diagonally.
3
Orient the napkin so the long side is on the left.
4
Fold the far corner of the napkin diagonally towards you and to the right so that the crease falls an inch or two short of the right-most corner and the newly formed point at the bottom is a few inches to the right of the left one.
5
Fold the right-most point towards you, pivoting at the same place the last fold pivoted. Use the finished napkin to drape the dinner place. Very classy and uncomplicated.
