The napkin bishop hat is another napkin origami classic.  It is fairly easy to learn.

Napkin Folding Bishop Hat

Now fold corner A to B, and fold corner C to D.   Next, rotate the napkin 90 degrees counterclockwise, then flip it over (left to right).

Now you will unfold two corners as shown by the arrows below.

Next, take the leftmost corner ("A") and tuck it under the flap in front.  Follow the pictures below.

Now flip the folded napkin over again, this time south to north. 

Then fold the rightmost corner under the flap in front, just like you did for corner A. 

Now place your hand into the bottom of the hat to expand it.  Then place it upright on the base.
