You can pretty much tie it any way you want. I found several tutorials online.
I chose to wing it!
I started by finding the middle of my scarf and laying it on the top of my head.
I then took the two ends, that were hanging down on each side of my head, and crossed them under my hair line by the nape of my neck. I went back and forth crossing at the top of my head and my neck line until I ran out of scarf.
You can see in the pictures [above] that I just tied it off on the side of my head, leaving some cute loose ends.
If you have bangs you can also tuck them in to keep them out of your face and it still looks great!
