I enjoy folding napkins in a different way when we have special occasions such as birthdays or anniversaries. This one is one of my favorites.
~The Crown~
First, fold your napkin in half.
Now, take the top left corner and fold it down.

Take the bottom right corner and fold it up.
It should look like this.

Now, turn it so it looks like this!
Turn it over

Take the bottom edge and fold it up, but leave the little point there as illustrated.

Flip it over so it appears as shown

Now, take the left side and pull up the right point and put it in there.
Like this!
This is how it should look!
Now, take the other point and tuck it in.

This is how the finished napkin should look.
The more you do, the faster you get!
