For a casual outdoor gathering, fashion fun napkins from bandanas! Look for inexpensive, cotton bandanas in a variety of colors at discount department stores. Wash and, if needed, quickly touch up with an iron.
With the wrong side up, fold the bandana in half diagonally.
Bring the point of the triangle over to the long, folded edge.
Scrunch the long edge together at the center and tie the bandana in a loose, overhand knot.
