This scarf fold is the foundation for many of my favorite ways to wear a silk square. Lay the scarf out on a flat surface (preferably one not covered in dog hair, unlike our bed) with the printed side down.
Fold two of the opposite corners in diagonally 1/2 to 2/3 of the way across.
Fold in again 2/3 from opposite corners. Don't worry if it's a little uneven; too much precision unermines that "just threw it on" effect we're going for.
