Did you ever wonder how the stacks of beverage napkins get so perfectly and decoratively arranged at high-end bars?
Here's the trick >>>> Place a stack (about 1-2") of napkins on a flat surface. Take a drinking glass and place it right-side-up on the napkins. Press down and rotate the glass about a quarter of a turn. The napkins should start to swirl. Lift up the glass, replace it on the napkins, press and rotate again. Repeat until the stack is swirled to your preference.
Note: you may want to discard the top napkin, if it gets too wrinkled from the rotations.
