Turning a square napkin into a cute envelope napkin isn’t all that hard. It honestly reminds me of making envelopes with paper as a kid. My biggest tip, use an iron.

With a square napkin, if you have a wrong side, face the wrong side up and turn until it is a shape of a diamond.

First, bring in the two sides where they overlap in the center (see photo).

Next, take the bottom triangle and move it up over the center, connecting the corners.. Iron

Now, you have choices. You can leave the “envelope” open and add a cute bunch of flowers or a menu. Or, you can fold it over and add a “seal” with a cute heart.
