Here are some instructions on how to do your hair to look like a bow or tied ribbon if you like that.
Start by sectioning your hair in two halves horizontally and pull each section into a ponytail. The top halve should be slightly larger than the bottom and should be about where you would put your ponytail regularly. The bottom halve should be a low ponytail so that basically you have two ponys one on top of the other. Make sure that you keep the two relatively close together to help with the next steps.
Now, pull the end of the top ponytail underneath the bottom ponytail and secure with bobby pins. If someone looks at you from the side it will look like a loop. The idea is to hide the bottom pony tail. Now, take the bottom tail and split it in two sections. Fold the right halve throught the loop you just made on the right side and do the same for the left halve. Let some of the ends fall out. You shoudl now have what looks like a ribbon tied into a bow.
For extra effect, leave out a few pieces of hair before you start and curl them. Also you can wrap a piece of hair around the top ponytail so everything is hidden from view.
