Napkin folding is usually considered only when setting a formal table or for a fancy party. But it can be a fun, creative outlet. It can also keep children entertained while others finish getting the meal ready. (Homemade place cards can also serve a similar purpose.) A related activity is towel or washcloth folding. It's not done as much in homes, but fancy hotels or cruise ships will sometimes fold the towels and washcloths, usually into animal shapes for the amusement of their guests. And it can be a fun, special treat for a child or guest.
