Drape the scarf around your neck, keeping the left side slightly shorter. Cross the right side over and begin to tie a knot, without pulling the right side all the way through. It then becomes an unfinished knot, with the two ends uneven. Drape the pulled-out portion over the knot, making it look like a half bow. To dress up the look, Salinger suggests adding a large broach to the top of the draped portion.
