Hi, I'm Kristen Smith-Hilton, global fashion stylist and president of Novella Style Group, with how to tie a square scarf. Tying a scarf that is square requires that you use your own personal style and ingenuity. When working with a square scarf, it's important that you leave enough material in order to tie it. Holding all four corners, you will take one corner, reach for the diagonal corner, drape it around your shoulders, and secure it in a knot over a shoulder of your choice, and adjust it to have a nice drape. And, you're all ready to go. I'm Kristen Smith-Hilton, and that is how to tie a square scarf.
