There are actually many different ways to tie a scarf. No one way is actually more right than any other but just depends on how you end up liking your scarf tied. A few examples of ways to tie your scarf are: The French knot; this is a simple way to tie the scarf. Fold the scarf in half put it over your shoulders and take one loose end piece and pull it over and under the scarf loop. Take the other piece and go under and over the same loop.
Another way is the neck wrap. Simply loop a long scarf once around your neck, make a half knot with the long ends near your neck and pull the fabric down. Then there is the classic loop. Put the scarf around your neck but pull one end down longer wrap that end around your neck and let both ends hang down.
